. Mike Carr/PU is on site working up the Hartmann screen to be mounted on the 2.5m telescope for work leading up to the next dark run. Caption precedes pictures . Mike has assembled the screen in the machine shop and is ready to transfer to enclosure. Another view. Steve Bastian was helping, too. Note the nice, clean machine shop area! . Pictures taken by Gretchen Van Doren/Apache Point Observatory.

Next: X--ray Activity and PMS stars . ... This has made the need to study the evolution of the rotation periods of stars, and hence the angular momentum, very clear. ... In the case of low mass pre--main sequence (PMS) stars, we seek to learn whether disks alone determine the angular momentum distribution when stars arrive on the main sequence. ... If one assumes that angular momentum is conserved from the natal cloud, then rotation periods exceeding breakup velocity are implied for PMS stars. ...
... Сегодня: 10 апреля 2016 г. До сих пор астрономы считали, что планеты рождаются внутри пылевых дисков, вращающихся вокруг молодых звезд. Причем процесс этот происходит относительно быстро - за 2-3 млн лет (до недавнего времени самым старым из протопланетных дисков считался диск, которому 10 млн лет), а потом пылевые диски исчезают (в большинстве случаев всю пыль "расхватывают" образовавшиеся планеты). ... Обнаружен старый протопланетный диск, в котором планеты не хотят рождаться . ...
