Pre-Main-Sequence Binary Stars

Annual Review of Astronomy and Astrophysics, 1994
The observational study of pre-main-sequence (PMS) binary stars is in many ways a very young field; most PMS binaries known today were discovered in the past decade. Nonetheless, T Tauri stars have been under study for more than a half century, and the serendipitous discovery of visual pairs has always been a by-product of their observation (e.g. Joy &

Infrared companions to pre-main sequence stars

Astrophysics and Space Science, 1988
We report 1.2, 1.6, 2.2 and 3.6 μm slit scan observations of the young low-luminosity stars Elias 22 (also known as GSS 31) in the Rho Ophiuchus dark cloud and Glass I in the Chamaeleon dark cloud. We discovered an infrared companion to Elias 22 at a projected separation of 2.0 arcsec (320 AU) and an optical/infrared companion to Glass I at a projected

Pre-Main Sequence Stars

1987
The IUE satellite has inaugurated a new era in the study of pre-main sequence (PMS) objects. IUE observations have revealed not just a new wavelength range but also a new temperature regime embracing physical phenomena that could not be studied before.

Pre-main Sequence Stars

2007
Herbig Ae/Be stars are the early-type pre-main sequence stars. Normally they are simply abbreviated as HES (Herbig emission-line stars) or HAEBE (Herbig Ae Be stars). (1960) originally defined HES by the following characteristics: (i) The spectral type is A or earlier, with emission lines. (ii) The star lies in an obscured region.

δ Scuti Pulsations in Pre-Main Sequence Stars

Astrophysics and Space Science, 2003
Intermediate mass pre-main sequence stars (1.5 to 5 M ⊙) cross the instability strip on their way to the main sequence. They are therefore expected to be pulsating in a similar way as the δ Scuti stars. In this review, I present the status of observational studies of pulsations in these stars, and comment on prospects for future investigations of these

Pre-Main-Sequence Stages of Stars

Publications of the Astronomical Society of Japan, 1965
Abstract Evolutionary model sequences of gravitationally contracting stars were calculated for masses, 0.4, 0.6, 1.0, 1.5, 2.0 and 3.0 M⊙, by using the surface condition based on the conventional mixing length theory of convection and assuming the contraction to be homologous. The mixing length was assumed to be equal to 1-pressure scale
