Models of very-low-mass stars, brown dwarfs and exoplanets. [PDF]
Philos Trans A Math Phys Eng Sci, 2012 Within the next few years, GAIA and several instruments aiming to image extrasolar planets will be ready. In parallel, low-mass planets are being sought around red dwarfs, which offer more favourable conditions, for both radial velocity detection and ...

Nearby Low-Mass Hypervelocity Stars [PDF]
EAS Publications Series, 2014 Hypervelocity stars are those that have speeds exceeding the escape speed and are hence unbound from the Milky Way. We investigate a sample of low-mass hypervelocity candidates obtained using data from the high-precision SDSS Stripe 82 catalogue, which ...

Deep inside low-mass stars [PDF]
Proceedings of the International Astronomical Union, 2008 Low-mass stars exhibit, at all stages of their evolution, the signatures of complex physical processes that require challenging modeling beyond standard stellar theory.

Simulating Radio Emission from Low-mass Stars [PDF]
The Astrophysical Journal, 2018 Abstract Understanding the origins of stellar radio emission can provide invaluable insight into the strength and geometry of stellar magnetic fields and the resultant space weather environment experienced by exoplanets. Here, we present the first model capable of predicting radio emission through the electron cyclotron maser instability

The Empirical Mass-Luminosity Relation for Low Mass Stars [PDF]
Astrophysics and Space Science, 2007 This work is devoted to improving empirical mass-luminosity relations and mass-metallicity-luminosity relation for low mass stars. For these stars, observational data in the mass-luminosity plane or the mass-metallicity-luminosity space subject to non ...

The Mass-Radius(-Rotation?) Relation for Low-Mass Stars [PDF]
The Astrophysical Journal, 2010 The fundamental properties of low-mass stars are not as well understood as those of their more massive counterparts. The best method for constraining these properties, especially masses and radii, is to study eclipsing binary systems, but only a small ...

The New Generation Planetary Population Synthesis (NGPPS). IV. Planetary systems around low-mass stars [PDF]
Astronomy & Astrophysics, 2021 Previous work concerning planet formation around low-mass stars has often been limited to large planets and individual systems. As current surveys routinely detect planets down to terrestrial size in these systems, a more holistic approach that reflects ...

The occurrence rate of giant planets orbiting low-mass stars with TESS [PDF]
, 2023 We present a systematic search for transiting giant planets ($0.6 R_{\rm J} \leq R_{\rm P} \leq 2.0 R_{\rm J}$) orbiting nearby low-mass stars ($M_{*} \leq 0.71 M_{\odot}$).

Pebble-driven planet formation around very low-mass stars and brown dwarfs [PDF]
Astronomy & Astrophysics, 2020 We conduct a pebble-driven planet population synthesis study to investigate the formation of planets around very low-mass stars and brown dwarfs in the (sub)stellar mass range between 0.01 M⊙ and 0.1 M⊙.
