Low Mass Stars with Mass Loss and Low-Luminosity Carbon Star Formation

1987
The effects of large carbon enrichments in static stellar envelopes were investigated, using new Los Alamos opacities (including low-temperature carbon and molecular opacities) and including carbon ionizations. To search for the production of low-mass, low-luminosity carbon stars, detailed stellar evolutionary computations were carried out for a grid ...

Low Mass Star Formation

1999
We review the basic ideas and key processes in low mass star formation with three goals. First, to introduce and explain the concepts and nomenclature frequently used in the literature. Second, to present a simplified, but (hopefully) coherent picture of low mass star formation. Third, to point out some of the important issues that are not yet resolved.

Low-Mass Star Formation: Theory

1999
Molecular clouds, the cradles of star birth, are supported against self-gravity in part by magnetic fields (McKee, this volume). In 1956, Mestel & Spitzer (see also Mestel 1965) introduced a mass scale associated with the amount of magnetic flux Φ threaded by a self-gravitating, electrically conducting, cloud.

Opacity problems in cool low mass stars

International Astronomical Union Colloquium, 1994
In this contribution we want to discuss M star atmospheres and their dependence on molecular opacities. A star belongs to the spectral class M if its optical and infrared spectrum shows strong bands of TiO and numerous strong metal lines so that for wavelengths < 4000 Å there is “hardly any flux left” (Jaschek & Jaschek 1987).
