Photosynthesis on habitable planets around low-mass stars [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We show that planets around M-dwarfs with $M_\star \lesssim 0.2 M_\odot$ may not receive enough photons in the photosynthetically active range of $400$-$750$ nm to sustain Earth-like biospheres.

Star Formation as Seen by Low Mass Stars
Acta 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 - 4Mʘ), metallicities (0:1 - 1 Zʘ) and ages (0:5 - 30 Myr).

PRE-MAIN SEQUENCE EVOLUTIONS OF SOLAR ABUNDANCE LOW MASS STARS [PDF]
Journal of Astronomy and Space Sciences, 2007 We present the Pre-Main Sequence (PMS) evolutionary tracks of stars with 0.065~5.0M_⨀. The models were evolved from the PMS stellar birthline to the onset of hydrogen burning in the core.

Galactic consequences of clustered star formation [PDF]
, 2009 If all stars form in clusters and both the stars and the clusters follow a power law distribution which favours the creation of low mass objects, then the numerous low mass clusters will be deficient in high mass stars.

Searching for signatures of planet formation in stars with circumstellar debris discs [PDF]
, 2015 (Abridged) Tentative correlations between the presence of dusty debris discs and low-mass planets have been presented. In parallel, detailed chemical abundance studies have reported different trends between samples of planet and non-planet hosts.

PARSEC V2.0: Stellar tracks and isochrones of low and intermediate mass stars with rotation [PDF]
Astronomy & Astrophysics, 2022 We present a new comprehensive collection of stellar evolutionary tracks and isochrones for rotating low- and intermediate-mass stars assembled with the updated version of PARSEC V2.0. This version includes our recent calibration of the extra mixing from

Characterizing K2 Candidate Planetary Systems Orbiting Low-mass Stars. II. Planetary Systems Observed During Campaigns 1–7 [PDF]
, 2017 We recently used near-infrared spectroscopy to improve the characterization of 76 low-mass stars around which K2 had detected 79 candidate transiting planets. 29 of these worlds were new discoveries that had not previously been published.

The Astrophysical Journal, 2023 By using direct N -body numerical simulations, we model the dynamical coevolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to investigate how different stellar components evolve during the merger, we

Exoplanets around Low-mass Stars Unveiled by K2 [PDF]
, 2017 We present the detection and follow-up observations of planetary candidates around low-mass stars observed by the K2 mission. Based on light-curve analysis, adaptive-optics imaging, and optical spectroscopy at low and high resolution (including radial ...
