On Low Mass AGB Stars [PDF]

open access: yesSymposium - 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.

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.

Carbon monoxide in low-mass dwarf stars [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2005
We compare high resolution infrared observations of the CO 3-1 bands in the 2.297-2.310 micron region of M dwarfs and one L dwarf with theoretical expectations. We find a good match between the observational and synthetic spectra throughout the 2000-3500K temperature regime investigated.
