Lithium 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 کاملThe Rotation of Low-Mass Pre-Main-Sequence Stars
Major photometric monitoring campaigns of star-forming regions in the past decade have provided rich rotation period distributions of pre-main-sequence stars. The rotation periods span more than an order of magnitude in period, with most falling between 1 and 10 days. Thus the broad rotation period distributions found in 100 Myr clusters are already established by an age of 1 Myr. The most rapi...
متن کاملRotation and activity of pre-main-sequence stars
Rotation and activity are key parameters in stellar evolution and can be used to probe basic stellar physics. Here we present a study of rotation (measured as projected rotational velocity v sin i) and chromospheric activity (measured as Hα equivalent width) based on an extensive set of high-resolution optical spectra obtained with the MIKE instrument on the 6.5m Magellan Clay telescope. Our ta...
متن کاملPre-Main-Sequence Stars with Photometric Rotation Periods
We use mid-IR (primarily 10 μm) photometry as a diagnostic for the presence of disks with inner cavities among 32 pre-main sequence stars in Orion and Taurus-Auriga for which rotation periods are known and which do not show evidence for inner disks at near-IR wavelengths. Disks with inner cavities are predicted by magnetic disk-locking models that seek to explain the regulation of angular momen...
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...
