Talk:NGC 1514

okay to update?

There have been a number of recent results that render some of the information on this page obsolete. (Disclaimer: some by me.) Anyone mind if I give it a fair update, including replacing the picture? Published references will be cited, of course.

I gave it an overhaul. Thanks. Praemonitus (talk) 14:06, 16 August 2020 (UTC)[reply]

Thanks for the update. However, there are still a couple of old details that are no longer our understanding.

1) The GAIA DR3 distance is about 454 pc (1480 ly), and carries an uncertainty of less than 1%. This number is used in the literature by Aller et al (2021). ^[1]

2) The 4-9 day period was a guess from a long time ago. Jones et al (2017) showed by radial velocity measurements of the pair that the period is 9 years (3306+/- 60 days). ^[2]
