Coronae of Zero/Low-metal, Low-mass Stars [PDF]
The Astrophysical Journal, 2019 Abstract Recent theoretical studies suggest the existence of low-mass, zero-metal stars in the current universe. To study the basic properties of the atmosphere of low-mass first stars, we perform one-dimensional magnetohydrodynamical simulations for the heating of coronal loops on low-mass stars with various metallicities.

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.

Symposium - International Astronomical Union, 1991 Recent results on low mass AGB stars are presented. Observed amounts of AGB mass loss imply that thermal pulses will only be encountered for stars of initial mass less than about 4M⊙ for Pop I and 3 M⊙ for Pop II. Mc – L, Me – τif, and Mc – Tb relations are summarized.

MgAl burning chain in M 54: The globular cluster-like properties of a nuclear star cluster
Astronomy & AstrophysicsIn this study, we present the chemical abundances of Fe, Mg, Al, Si, and K for a sample of 233 likely member stars of M 54. All the stars were observed with the FLAMES high-resolution multi-object spectrograph mounted at the VLT.

The Astrophysical Journal, 2023 By using direct N -body numerical simulations, we model the dynamical coevolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to investigate how different stellar components evolve during the merger, we

Evolution and Nucleosynthesis of Primordial Low‐Mass Stars
The Astrophysical Journal, 2004 We discuss in detail the evolutionary properties of low mass stars M< 1 M(Solar) having metallicity lower than Z=10^(-6) from the pre- main sequence up to (almost) the end of the Asymptotic Giant Branch phase. We also discuss the possibility that the large [C,N/Fe] observed on the surface of the most Iron poor star presently known, HE0107-5240, may ...

Facing the phase: Gravity-mode offset and buoyancy glitches in stars on the red-giant branch
Astronomy & AstrophysicsContext. With the increasing precision of asteroseismic observations, it becomes possible to reliably measure oscillation properties of an increasing number of stars. Interpreting these measurements requires a good theoretical understanding of their link
