Accretion onto Pre-Main-Sequence Stars

Annual Review of Astronomy and Astrophysics, 2016
Accretion through circumstellar disks plays an important role in star formation and in establishing the properties of the regions in which planets form and migrate. The mechanisms by which protostellar and protoplanetary disks accrete onto low-mass stars are not clear; angular momentum transport by magnetic fields is thought to be involved, but the ...

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 &
