EPJ Web of Conferences, 2013 Searching for planets around stars with different masses probes the outcome of planetary formation for different initial conditions. The low-mass M dwarfs are also the most frequent stars in our Galaxy and potentially therefore, the most frequent planet ...

Habitability Properties of Circumbinary Planets
The Astronomical Journal, 2017 Abstract It is shown that several habitability conditions (in fact, at least seven such conditions) appear to be fulfilled automatically by circumbinary planets of main-sequence stars (CBP-MS), whereas on Earth, these conditions are fulfilled only by chance.

The extrasolar planet Gliese 581d: a potentially habitable planet? [PDF]
Astronomy & Astrophysics, 2010 The planetary system around the M star Gliese 581 contains at least three close-in potentially low-mass planets, GL 581 c, d, and e. In order to address the question of the habitability of GL 581 d, we performed detailed atmospheric modeling studies for several planetary scenarios.

The Astrophysical JournalPlanets orbiting in the habitable zones of white dwarfs have recently been proposed as promising targets for biosignature searches. However, since the white dwarf habitable zone resides at 0.01–0.1 au, planets residing there are subject to tidal heating ...

Novel Atmospheric Dynamics Shape the Inner Edge of the Habitable Zone around White Dwarfs
The Astrophysical JournalWhite dwarfs offer a unique opportunity to search nearby stellar systems for signs of life, but the habitable zone around these stars is still poorly understood.

Planets in habitable zones: [PDF]
Astronomy & Astrophysics, 2003 The recently discovered planetary system in the binary GamCep was studied concerning its dynamical evolution. We confirm that the orbital parameters found by the observers are in a stable configuration. The primary aim of this study was to find stable planetary orbits in a habitable region in this system, which consists of a double star (a=21.36 AU ...

The Importance of the Upper Atmosphere to CO/O2 Runaway on Habitable Planets Orbiting Low-mass Stars
The Astrophysical Journal Letters, 2023 Efforts to spectrally characterize the atmospheric compositions of temperate terrestrial exoplanets orbiting M dwarf stars with JWST are now underway.

Water Evolution and Inventories of Super-Earths Orbiting Late M Dwarfs
The Astrophysical JournalSuper-Earths orbiting M dwarf stars may be the most common habitable planets in the Universe. However, their habitability is threatened by intense irradiation from their host stars, which drives the escape of water to space and can lead to surface ...

No Transits of Proxima Centauri Planets in High-Cadence TESS Data
Frontiers in Astronomy and Space Sciences, 2021 Proxima Centauri is our nearest stellar neighbor and one of the most well-studied stars in the sky. In 2016, a planetary companion was detected through radial velocity measurements.

Eccentricity formation and habitable planets in OGLE-06-109L system
EPJ Web of Conferences, 2011 Recent observation of microlensing technique reveals two giant planets at 2.3 AU and 4.6 AU around the star OGLE-06-109L. We investigate the eccentricity formation of these two planets, and find that planetary scattering or resonance crossing may be the ...
