Hydrogen dominated atmospheres on terrestrial mass planets: evidence, origin and evolution

JE Owen, IF Shaikhislamov, H Lammer, L Fossati… - Space Science …, 2020 - Springer
The discovery of thousands of highly irradiated, low-mass, exoplanets has led to the idea
that atmospheric escape is an important process that can drive their evolution. Of particular …

Partially ionized plasmas in astrophysics

JL Ballester, I Alexeev, M Collados, T Downes… - Space Science …, 2018 - Springer
Partially ionized plasmas are found across the Universe in many different astrophysical
environments. They constitute an essential ingredient of the solar atmosphere, molecular …

The habitability of proxima centauri bI. irradiation, rotation and volatile inventory from formation to the present

I Ribas, E Bolmont, F Selsis, A Reiners… - Astronomy & …, 2016 - aanda.org
Proxima b is a planet with a minimum mass of 1.3M⊕ orbiting within the habitable zone (HZ)

sequence stars. Our aim is to use rotational evolution models to constrain the mass loss …

Magnetic moment and plasma environment of HD 209458b as determined from Lyα observations

KG Kislyakova, M Holmström, H Lammer, P Odert… - Science, 2014 - science.org
Transit observations of HD 209458b in the stellar Lyman-α (Lyα) line revealed strong
absorption in both blue and red wings of the line interpreted as hydrogen atoms escaping …

Effects of M dwarf magnetic fields on potentially habitable planets

AA Vidotto, M Jardine, J Morin, JF Donati… - Astronomy & …, 2013 - aanda.org
We investigate the effect of the magnetic fields of M dwarf (dM) stars on potentially habitable
Earth-like planets. These fields can reduce the size of planetary magnetospheres to such an …

Atmosphere expansion and mass loss of close-orbit giant exoplanets heated by stellar XUV. II. Effects of planetary magnetic field; structuring of inner magnetosphere

ML Khodachenko, IF Shaikhislamov… - The Astrophysical …, 2015 - iopscience.iop.org
This is the second paper in a series where we build a self-consistent model to simulate the
mass-loss process of a close-orbit magnetized giant exoplanet, so-called hot Jupiter (HJ). In …

Stellar wind effects on the atmospheres of close-in giants: a possible reduction in escape instead of increased erosion

AA Vidotto, A Cleary - Monthly Notices of the Royal Astronomical …, 2020 - academic.oup.com
The atmospheres of highly irradiated exoplanets are observed to undergo hydrodynamic
escape. However, due to strong pressures, stellar winds can confine planetary atmospheres …

Indications for an influence of hot Jupiters on the rotation and activity of their host stars

K Poppenhaeger, SJ Wolk - Astronomy & Astrophysics, 2014 - aanda.org
Context. The magnetic activity of planet-hosting stars is an important factor for estimating the
atmospheric stability of close-in exoplanets and the age of their host stars. It has long been …

Hubble Space Telescope detection of oxygen in the atmosphere of exoplanet HD 189733b

L Ben-Jaffel, GE Ballester - Astronomy & Astrophysics, 2013 - aanda.org
Detecting heavy atoms in the inflated atmospheres of giant exoplanets that orbit close to
their parent stars is a key factor for understanding their bulk composition, their evolution, and …
