Nucleosynthesis in low-mass stars: Shedding light on the cosmic origin of heavy elements [PDF]
Low-mass, low-metallicity stars while evolving through the asymptotic giant branch (AGB) phase undergo significant nucleosynthesis producing the majority of slow (s-) and intermedite (i-) neutron capture elements.

Recent surveys of the Magellanic Clouds have revealed a subtype of Wolf-Rayet (WR) star with peculiar properties. WN3/O3 spectra exhibit both WR-like emission and O3 V-like absorption - but at lower luminosity than O3 V or WN stars.

Low-mass bare strange stars [PDF]
Strange stars with low masses are suggested to exist in reality, the origin of which could be via accretion-induced collapse (AIC) of white dwarfs. Such a strange star is likely bare, and would thus spin very fast, even to a period of < 0.1 ms. Strange stars with low masses may differ from those with solar-masses in various astrophysical appearances.

Tidally Delayed Spin-Down of Very Low Mass Stars
Very low-mass main-sequence stars reveal some curious trends in observed rotation period distributions that require abating the spin-down that standard rotational evolution models would otherwise imply.

Discovery of a Proto–White Dwarf with a Massive Unseen Companion
We report the discovery of SDSS J022932.28+713002.7, a nascent extremely low-mass (ELM) white dwarf (WD) orbiting a massive (>1 M _⊙ at 2 σ confidence) companion with a period of 36 hr.

Constraining Snyder and GUP models with low-mass stars
We investigate the application of an equation of state that incorporates corrections derived from the Snyder model (and the Generalized Uncertainty Principle) to describe the behaviour of matter in a low-mass star.

On the lifetime of discs around late type stars
We address the question of whether protoplanetary discs around low mass stars (e.g. M-dwarfs) may be longer lived than their solar-type counterparts. This question is particularly relevant to assess the planet-making potential of these lower mass discs ...

Evidence for a constant IMF in early-type galaxies based on their X-ray binary populations [PDF]
A number of recent studies have proposed that the stellar initial mass function (IMF) of early type galaxies varies systematically as a function of galaxy mass, with higher mass galaxies having bottom heavy IMFs.
