Manfred Cuntz is a German astrophysicist based in the United States since 1988. He is a Distinguished Professor of physics at the University of Texas at Arlington (UTA). His primary research interests include stellar astrophysics, astrobiology, and planetary habitability. In 2023, he became a fellow with the Committee for Skeptical Inquiry.[2]

Early life and education

[edit]

Manfred Cuntz was born on April 21, 1958, in Landau in der Pfalz in Rhineland-Palatinate, Germany.[citation needed] He was the first-born son of Gerhard Hermann Cuntz and Irene Emma Cuntz (née Messerschmitt) and was raised in Bornheim. His family's business was in viticulture and livestock agriculture. As the eldest son, Cuntz would have inherited the farm. Early on, however, his family deemed him unsuitable for farm work and, instead, had him focus on his education.[3]

Cuntz attended secondary school at the Eduard-Spranger Gymnasium in Landau, from which he graduated with the Abitur in 1977. Even though he was a dedicated student, especially in mathematics and the natural sciences, academic success did not come easily to Cuntz in all subjects. In fact, he had to repeat the eighth grade. After that, however, he became a top student, especially in the last years of secondary school when he was able to focus on the subjects of mathematics, chemistry, and social studies.[3]

Cuntz went on to study physics and astronomy at the University of Heidelberg, Germany.[3] There, he earned a Diplom (equivalent to having earned both a U.S. bachelor's and master's degrees) in Physics in 1985. He earned his PhD (Dr. rer. nat.) in Astronomy from the same university in 1988[1] with a dissertation on stellar atmospheric heating and stellar winds, titled Generation of Extended Chromospheres and Mass Loss of Late-Type Giant Stars due to Acoustic Shock Waves.[4]

Career

[edit]

After completing his degrees at the University of Heidelberg, Manfred Cuntz moved to the United States. He held positions as a postdoctoral research assistant in the Joint Institute for Laboratory Astrophysics (JILA) at the University of Colorado from 1989 to 1991 and at the High Altitude Observatory (HAO) from 1992 to 1993, a division of the National Center for Atmospheric Research (NCAR). In 1994, he returned to the University of Heidelberg as Habilitation Fellow. Then, he joined the Center for Space Plasma and Aeronomic Research at the University of Alabama in Huntsville from 1996 until 1999. In 2000, Cuntz became a visiting professor in the physics department of the University of Texas at Arlington, then moved up the tenure track to become Professor in 2012.[1]

He is an editor of the journal Astronomische Nachrichten (Astronomical Notes).[5]

Research

[edit]

Cuntz's research focuses on the probability and possible distribution of extraterrestrial life on extrasolar planets and moons and "is based on a pure theoretical approach."[6]

In 2000, Manfred Cuntz, together with Steven Saar of the Harvard-Smithsonian Center for Astrophysics, made predictions "that planetary magnetic fields could produce detectable effects on stars". This phenomenon was later observed in 2003 by E. Shkolnik of the University of British Columbia, Canada.[7] Cuntz also argues that "extreme magnetic protection by a powerful planetary magnetic dipole field" could increase the probability that a planet is habitable even if it is subject to "extreme ultraviolet and x-ray" radiation from its star.[8]

In January of 2012, Manfred Cuntz and Billy Quarles, as part of a team of researchers from the University of Texas Arlington, "gained international recognition for identifying the possibility of a habitable moon within the orbit of the recently discovered planet called Kepler-16b." The scientists used data from NASA's Kepler space telescope to analyze the possibilities of an Earth-like planet or moon to sustain life within the Kepler binary star system. They relied on Cuntz’s expertise in astrobiology "to develop a range within the system where life would be able to exist."[9] According to Cuntz, "the planet's critical feature to sustain life would be liquid water"; and he suggests those "life form[s] could be along the lines of a plant or bacteria."[10]

Cuntz and Quarles collaborated again as co-authors on a study led by Oshina Jagtap published in 2021, which "explores the possibility of exomoons in a planetary system named HD 23079, located in Reticulum, a small constellation in the southern sky." This system is of interest because it contains a planet similar to Jupiter. Cuntz argues that since "Jupiter [is] a host to four planet-size moons (among many other moons), with two of them (Europa and Ganymede) having a significant chance of being habitable," gas giants in other star systems which could host an Earth-sized moon with the conditions for liquid water.[11]

To assist astrophysicists in identifying habitable zones, Cuntz developed "BinHab, a new online tool that can be used to calculate the regions of binary systems favorable for life" in 2014. According to Cuntz, the program considers both "the amounts of stellar radiation, which provides a favorable planetary climate for life, and the gravitational influence of both stars on an existing planet." The interim dean of the UTA College of Science, James Grover, said this tool "holds enormous potential for those who study space in the search for life."[6]

Cuntz has worked with other researchers to "examined both the damaging and the favourable effects of ultraviolet (UV) radiation from stars on DNA molecules" and how it could affect "potential carbon-based extraterrestrial life forms in the habitable zones around other stars."[12] A study conducted by Cuntz, Satoko Sato, and researchers from the University of Guanajuato in Mexico found that F-type star systems "may [...] be a good place to look for habitable planets" because they have a larger "area where conditions are right for general Earth-type planets to develop and sustain life" than smaller, cooler stars like our Sun. The research demonstrated that the damage to DNA from UV radiation on planets "in the outer portions of F-star habitable zones" was "similar to the damage on Earth, if Earth did not have an atmosphere."[13]

In 2016, Cuntz, while collaborating with Edward Guinan at Villanova University, explored which types of stars are best suited to offer prospects of habitability. They argued in favor of orange dwarfs, namely low-luminosity G-type and K-type stars; the related planetary condition is sometimes also called superhabitability. Guinan pointed out that "[m]any K-stars can be much older than our Sun. So, if life formed and evolved on habitable zone planet hosted by a[n] old K-star ... a few to several billions of years older than the Sun; it could maybe even harbor intelligent life."[14]

In 2022, while collaborating with four of his students, Cuntz published an early catalog of planet-hosting triple star systems, a relatively rare astronomical phenomenon.[15]

Community involvement

[edit]

Cuntz actively participates in education and public outreach (EPO). He has worked with The Planetarium at University of Texas at Arlington to create several shows. A 45-minute film titled Magnificent Sun, for which Cuntz co-authored the script, is intended to allow "the general public to share information and excitement about solar physics."[16] Another show, Cosmic CSI: Looking for Life in the Universe, aims to present Cuntz's "research in astrobiology to the rest of the community."[17] Additionally, he was the Principal Investigator for the development of a 3-D planetarium film "based on NASA's research and outreach mission, Stratospheric Observatory for Infrared Astronomy, or SOFIA."[18]

Outside of his academic work, Cuntz pursues examination of fake news in science by writing articles in the journal Skeptical Inquirer.[19] This has included articles about misguided criticism of the work of Albert Einstein[20] and commentary about responses from religious groups regarding the James Webb Space Telescope (JWST).[21]

Literary influences

[edit]

A publication by Cuntz on possible Earth-like planets in the star system 55 Cancri served as inspiration for Kenneth E. Ingle's science fiction novel First Contact: Escape to 55 Cancri.[22]

Cuntz has also chosen to explore urban legends. He offered contributions to Rolf Wilhelm Brednich, at that time a professor of Folklore / European ethnology at the University of Göttingen in Germany, for one of his books on modern legends.[23]

In 2024, Cuntz published his first kids book, titled Fun with Three Suns in the Sky, aimed at sparking interest in young children in astronomy and space science. The storyline of the book is loosely modeled after the Alpha Centauri system.[24]
