Annual Review of Astronomy and Astrophysics, 1987
Very low mass (VLM) stars, which we define here somewhat arbitrarily as those with masses ;$ 0.3 M 0' pose some of the more interesting problems in stellar astrophysics. The physics of their envelopes and atmospheres are more complicated and their structures less well modeled than their more massive counterparts.

Discovery of ubiquitous lithium production in low-mass stars
Nature Astronomy, 2020The vast majority of stars with mass similar to that of the Sun are expected to destroy lithium (Li) gradually over the course of their lives, via low-temperature nuclear burning.

Low mass stars contribute an important fraction to the mass of our Galaxy. Due to the faintness of these stars a direct investigation of their space distribution and kinematics can be carried out only in the immediate solar neighbourhood. This fact emphasizes the importance of the “Third Catalogue of Nearby Stars” (CNS3) as a probe of the stellar ...

Origins of life and evolution of the biosphere, 1997
Recent evidence indicates that most low mass stars in the Galaxy (< 5 M [symbol: see text]) form alongside massive stars in clusters embedded in giant molecular clouds. Once their parental gas is removed, the fate of these clusters is to disperse and blend into the field population of the galactic disk.

More and more observational hints of quark stars are proposed these years though pulsars are considered conventionally to be normal neutron stars. The existence of low-mass quark stars is a direct consequence of the possibility that pulsar-like stars are actually quark stars, because of the ability that quark matter can confine itself by color ...

Low- and Intermediate-Mass Stars
2018Energy in stars is provided by nuclear reactions, which, in many cases, produce radioactive nuclei. When stable nuclei are irradiated by a flux of protons or neutrons, capture reactions push stable matter out of stability into the regime of unstable species. The ongoing production of radioactive nuclei in the deep interior of the Sun via proton-capture

Pregalactic-primordial low-mass stars
Astrophysics and Space Science, 1987The Main-Sequence positions as well as the evolutionary behavior of Population III stars up to an evolution age of 2×1010 yr, taking this time as the age of the Universe, have been investigated in the mass range 0.2 and 0.8M⊙. While Population III stars with masses greater than 0.3M⊙ develop a radiative core during the approach to the Main Sequence ...

Mass Determination of Very Low Mass Stars
1995We discuss the precision achieved with the present observing techniques for the mass determination of low and very low mass stars. We show the gain that will be achieved with high precision radial velocity measurements combined with diffraction-limited imaging with 8-m class telescopes and the VLTI.
