0942 . 7 − 7726 AB : an isolated pre - main - sequence wide binary
We report the discovery of two young M-dwarfs, RX J0942.7−7726 (M1) and 2MASS J09424157−7727130 (M4.5), that were found only 42 arcsec apart in a survey for pre-main-sequence stars surrounding the open cluster ηChamaeleontis. Both stars have congruent proper motions and near-infrared photometry. Medium-resolution spectroscopy reveals that they are coeval (age 8–12 Myr), codistant (100–150 pc) a...
متن کاملKH 15D: Gradual Occultation of a Pre–Main-Sequence Binary
We propose that the extraordinary “winking star” KH 15D is an eccentric pre–mainsequence binary that is gradually being occulted by an opaque screen. This model accounts for the periodicity, depth, duration, and rate of growth of the modern eclipses; the historical light curve from photographic plates; and the existing radial velocity measurements. It also explains the re-brightening events tha...
متن کاملLithium Depletion Boundary in a Pre-main Sequence Binary System
A lithium depletion boundary is detected in HIP 112312 (GJ 871.1 A and B), a ∼ 12 Myr old pre-main sequence binary system. A strong (EW≈ 300 mÅ) Li 6708 Å absorption feature is seen at the secondary (∼M4.5) while no Li 6708 Å feature is detected from the primary (∼M4). The physical companionship of the two stars is confirmed from common proper motions. Current theoretical pre-main sequence evol...
متن کاملBinary Masses as a Test for Pre–Main-Sequence Tracks
Observations of binaries have traditionally provided the means for ascertaining stellar masses. Here, we use the published data on 8 pre–main-sequence pairs to gauge the accuracy of our own, recently calculated, evolutionary tracks (Palla & Stahler 1999). We consider both eclipsing, double-lined spectroscopic binaries, which provide the mass of each star separately, and non-eclipsing, double-li...
متن کاملPre-main-sequence Lithium Depletion
In this review I briefly discuss the theory of pre-main-sequence (PMS) Li depletion in low-mass (0.075 < M < 1.2M⊙) stars and highlight those uncertain parameters which lead to substantial differences in model predictions. I then summarise observations of PMS stars in very young open clusters, clusters that have just reached the ZAMS and briefly highlight recent developments in the observation ...
