Talk:HD 98800

Location

HD 98800 is located in constellation Crater. But it belongs to TW Hydrae association. So we have dealings with a misapprehension. —Preceding unsigned comment added by 195.62.14.216 (talk) 15:08, 7 April 2008 (UTC)[reply]

[1] says it's in Crater as well, but it's also in TW Hydrae, and TW Hydrae is in Hydra. I don't understand. --Stlemur (talk) 15:59, 7 April 2008 (UTC)[reply]

SIMBAD says the same. I think, the star is situated on the border of the constellation. 195.62.14.216 (talk) 13:58, 8 April 2008 (UTC)[reply]

A constellation is a grouping of stars as they appear on the sky. TW Hydrae is a physical association of stars in space that are likely to have formed at the same time in the same cluster. See Moving_group#Kinematic_groups for more details. AstroMark (talk) 05:45, 16 January 2012 (UTC)[reply]

this system features an exceptionally strange protoplanetary disk ... Normally, a protoplanetary disk rests along the same plane as the orbital plane of its binary star hosts. But not HD 98800—its protoplanetary disk rests perpendicularly to the plane of the binary pair at a right angle. It’s in a polar configuration, where instead of running east-west, the disk is running north-south, so to speak J mareeswaran (talk) 03:54, 15 January 2019 (UTC)[reply]
