Evaluating Serpentinization as a Source of Phosphite to Microbial Communities in Hydrothermal Vents

Geobiology, Volume 23, Issue 2, March/April 2025.
ABSTRACT Previous studies have documented the presence of phosphite, a reduced and highly soluble form of phosphorus, in serpentinites, which has led to the hypothesis that serpentinizing hydrothermal vents could have been an important source of bioavailable phosphorus for early microbial communities in the Archean.

The mass-period distribution of close-in exoplanets

, 2011
The lower limit to the distribution of orbital periods P for the current population of close-in exoplanets shows a distinctive discontinuity located at approximately one Jovian mass. Most smaller planets have orbital periods longer than P~2.5 days, while

Is OSSO a Significant Contributor to the Unknown UV Absorber in Venus' Atmosphere?

Geophysical Research Letters, Volume 52, Issue 4, 28 February 2025.
Abstract It has been proposed that two isomers of the SO dimer (cis‐ and trans‐OSSO) are candidates for the unknown UV absorber in Venus' atmosphere because they have a good spectral match with the absorber, despite the low concentrations predicted by 1D photochemical models.

Infrared-radio-follow-up observations for detection of the magnetic radio emission of extra solar planets: a new window to detect exoplanets

Frontiers in Astronomy and Space Sciences
There are several methods for indirectly detecting exoplanets, such as transit, radial velocity, astrometry, and the conventional gravitational microlensing approach.

Magnetic Scaling Laws for the Atmospheres of Hot Giant Exoplanets

, 2011
We present scaling laws for advection, radiation, magnetic drag and ohmic dissipation in the atmospheres of hot giant exoplanets. In the limit of weak thermal ionization, ohmic dissipation increases with the planetary equilibrium temperature (T_eq ...

Superhabitable Planets Around Mid‐Type K Dwarf Stars Enhance Simulated JWST Observability and Surface Habitability

Astronomische Nachrichten, Volume 346, Issue 2, February 2025.
ABSTRACT In our search for life beyond the Solar System, certain planetary bodies may be more conducive to life than Earth. However, the observability of these “superhabitable” (SH) planets in the habitable zones around K dwarf stars has not been fully modeled. This study addresses this gap by modeling the atmospheres of SH exoplanets.
