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,

Wide binary stars in the Galactic field : a statistical approach [PDF]
, 2010 This thesis focuses on the statistical properties of wide binary (WB) star systems in the Galactic field. With projected separations larger than 200 AU and, consequently, having very low binding energies, WB are sensitive probes of the Galactic ...

Widely separated binary systems of very low-mass stars
, 2005 In this paper we review some recent detections of wide binary brown dwarf systems and discuss them in the context of the multiplicity properties of very low-mass stars and brown ...

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.

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.

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.

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.

A survey for low mass spectroscopic binary stars in the young clusters around sigma Orionis and lambda Orionis [PDF]
, 2008 We have obtained multi-epoch, high-resolution spectroscopy of 218 candidate low-mass stars and brown dwarfs in the young clusters around sigma Ori and lambda Ori. We find that 196 targets are cluster members based on their radial velocity, the equivalent
