Pulsation in extremely low-mass helium stars [PDF]

open access: bronzeMonthly Notices of the Royal Astronomical Society, 2013
AbstractWe explore the stability of extremely low-mass stars (M < 0.25 M⊙) across a wide range of composition, effective temperature, and luminosity. We identify the instability boundaries associated with radial oscillations. These are a strong function of both composition and radial order (0 ≤ n ≤ 13).

Star Formation as Seen by Low Mass Stars

open access: yesActa Polytechnica CTU Proceedings, 2014
Using the Hubble Space Telescope (HST) we have characterised and compared the physical properties of a large sample of pre-main sequence (PMS) stars spanning a wide range of masses (0:5 - 4M<sub>ʘ</sub>), metallicities (0:1 - 1 Z<sub>ʘ</sub>) and ages (0:5 - 30 Myr).

Evolution and Nucleosynthesis of Primordial Low‐Mass Stars

open access: yesThe 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 ...

Rotation of Low-mass Stars in Taurus with K2 [PDF]

open access: yesThe Astronomical Journal, 2020
Abstract We present an analysis of K2 light curves (LCs) from Campaigns 4 and 13 for members of the young (∼3 Myr) Taurus association, in addition to an older (∼30 Myr) population of stars that is largely in the foreground of the Taurus molecular clouds.
