Mass-radius relation of low and very low-mass stars revisited with the VLTI [PDF]

, 2009
International audienceWe measured the radii of 7 low and very low-mass stars using long baseline interferometry with the VLTI interferometer and its VINCI and AMBER near-infrared recombiners.

DCT astrometry of very low-mass stars [PDF]

, 2016
Very low-mass stars (VLMs) are the smallest, least luminous stars in our galaxy, but nonetheless form one of the dominant (baryonic) populations. Precise distances and kinematics of VLMs can provide constraints on the smallest extremes of star formation,

Influence of the initial orbital period and accretion efficiency on the low-mass binary evolution [PDF]

Serbian Astronomical Journal, 2021
This paper presents detailed evolutionary models of low-mass binary systems (1.25 + 1 M⊙) with initial orbital periods of 10, 50 and 100 days and accretion efficiency of 10%, 20%, 50%, and a conservative assumption.

A study of U Aquarii and the nucleosynthesis of neutrons and S-process elements in evolved stars of low mass [PDF]

, 2014
The origin of the extreme hydrogen deficiency observed in the R Coronae Borealis (RCrB) stars remains poorly understood. A likely mechanism for producing this deficiency is one whereby the original hydrogen envelope of the star is engulfed and ...

Comparing the asteroseismic properties of pulsating extremely low-mass pre-white dwarf stars and δ Scuti stars

EPJ Web of Conferences, 2017
We present the first results of a detailed comparison between the pulsation properties of pulsating Extremely Low-Mass pre-white dwarf stars (the pre-ELMV variable stars) and δ Scuti stars.

Life Cycle of a Low Mass Stars [PDF]

, 2023
In the present work, I shall explain the gravity mechanism and life cycle of a low mass Stars. For this purpose, some mathematical equations, and MATLAB Program could be used to draw the shape of a gravity as a dark fabric distortion in three dimensions ...

Jsolated Stars of Low Metallicity

Galaxies, 2018
We study the effects of a reduced mass-loss rate on the evolution of low metallicity Jsolated stars, following our earlier classification for angular momentum (J) isolated stars.

PRE-MAIN SEQUENCE EVOLUTIONS OF SOLAR ABUNDANCE LOW MASS STARS [PDF]

Journal of Astronomy and Space Sciences, 2007
We present the Pre-Main Sequence (PMS) evolutionary tracks of stars with 0.065~5.0M_⨀. The models were evolved from the PMS stellar birthline to the onset of hydrogen burning in the core.

Evolutionary effects of mass loss in low-mass stars [PDF]

International Astronomical Union Colloquium, 1981
AbstractThe effects of mass loss on the evolution of low-mass stars (actual mass smaller than 1.4 Mʘ) are reviewed. The case of globular cluster stars is discussed in some detail, and it is shown that evolutionary theory sets quite precise limits to the mass-loss rate in population II red giants.
