Pre-main-sequence Evolution

Nature, 1967
IT is several years since the first discovery of stellar clusters which appeared to be so young that a number of stars in them were still in the process of contracting onto the main sequence1–4. The first theoretical model covering the evolution of stars, on the assumption that their self gravitational energy is the only energy source available, was ...

Pre-Main-Sequence Outflows

Astrophysics and Space Science, 1995
In the 3 decades since winds from young stars were discovered, there have been many observations of bipolar molecular flows and ionized jets, and it has been recognized that outflows are intimately linked to star formation. Despite many observational clues and theoretical ideas, we still do not have a fully coherent picture of the outflow process.

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 &

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 Evolution

2002
The matter in the Universe (its barionic component) is concentrated mainly in stars. Inside galaxies, stars contain more than 90% of the matter, and in galactic clusters, due to the existence of intercluster gas, stars contain more than 70% of the matter. The presence of heavy elements (heavier than carbon) in the intercluster gas, with an abundance of
