A Chandra X-ray study of the young star cluster NGC 6231: low-mass population and initial mass function [PDF]
, 2016 NGC6231 is a massive young star cluster, near the center of the Sco OB1 association. While its OB members are well studied, its low-mass population has received little attention.

Low-mass Star Formation: Observations [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractI briefly review recent observations of regions forming low mass stars. The discussion is cast in the form of seven questions that have been partially answered, or at least illuminated, by new data. These are the following: where do stars form in molecular clouds; what determines the IMF; how long do the steps of the process take; how efficient

THE INNER EDGE OF THE HABITABLE ZONE FOR SYNCHRONOUSLY ROTATING PLANETS AROUND LOW-MASS STARS USING GENERAL CIRCULATION MODELS [PDF]
, 2016 Terrestrial planets at the inner edge of the habitable zone (HZ) of late-K and M-dwarf stars are expected to be in synchronous rotation, as a consequence of strong tidal interactions with their host stars. Previous global climate model (GCM) studies have

The Initial Mass Functions in the Super-Star-Clusters NGC 1569A and NGC 1705-1 [PDF]
, 1998 I use recent photometric and stellar velocity dispersion measurements of the super-star-clusters (SSCs) NGC 1569A and NGC 1705-1 to determine their present-day luminosity/mass (L_V/M) ratios. I then use the inferred L_V/M ratios, together with population

Formation and composition of planets around very low mass stars [PDF]
, 2016 Context. The recent detection of planets around very low mass stars raises the question of the formation, composition, and potential habitability of these objects. Aims.

Self-consistent evolution of accreting low-mass stars and brown dwarfs [PDF]
, 2016 We present self-consistent calculations coupling numerical hydrodynamics simulations of collapsing pre-stellar cores and stellar evolution models of accreting objects.

Postmerger Mass Ejection of Low-mass Binary Neutron Stars [PDF]
Astrophysical Journal, 2020 We study the postmerger mass ejection of low-mass binary neutron stars (NSs) with the system mass of 2.5 M ⊙ and subsequent nucleosynthesis by performing general-relativistic, neutrino-radiation viscous-hydrodynamics simulations in axial symmetry.

Adiabatic Mass Loss in Binary Stars. IV. Low- and Intermediate-mass Helium Binary Stars
The Astrophysical Journal Supplement SeriesThe unstable mass transfer situation in binary systems will asymptotically cause the adiabatic expansion of the donor star and finally lead to the common envelope phase.
