HARPS-N @ TNG, two year harvesting data : performances and results [PDF]

, 2014
The planet hunter HARPS-N[1], in operation at the Telescopio Nazionale Galileo (TNG)[13] from April 2012 is a highresolution spectrograph designed to achieve a very high radial velocity precision measurement thanks to an ultra stable environment and in a

Using dimers to measure biosignatures and atmospheric pressure for terrestrial exoplanets [PDF]

, 2014
We present a new method to probe atmospheric pressure on Earth-like planets using (O-O) dimers in the near-infrared. We also show that dimer features could be the most readily detectable biosignatures for Earth-like atmospheres and may even be detectable

Chemical modeling of exoplanet atmospheres [PDF]

, 2014
International audienceThe past twenty years have revealed the diversity of planets that exist in the Universe. It turned out that most of exoplanets are different from the planets of our Solar System and thus, everything about them needs to be explored ...

The Effects of Non-ideal Mixing in Planetary Magma Oceans and Atmospheres

The Astrophysical Journal
Sub-Neptunes with hydrogen-rich envelopes are expected to sustain long-lived magma oceans that continuously exchange volatiles with their overlying atmospheres.

Earth as a Transiting Exoplanet: A Validation of Transmission Spectroscopy and Atmospheric Retrieval Methodologies for Terrestrial Exoplanets

The Planetary Science Journal, 2023
The James Webb Space Telescope (JWST) will enable the search for and characterization of terrestrial exoplanet atmospheres in the habitable zone via transmission spectroscopy.

Soot Planets Instead of Water Worlds

The Astrophysical Journal Letters
Some low-density exoplanets are thought to be water-rich worlds that formed beyond the snow line of their protoplanetary disk, possibly accreting coequal portions of rock and water.

Propagation Dynamics of Fast Electron Beam and Its Electron Cyclotron Maser Emission

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Fast electron beams (FEBs) and coherent radio bursts both are very common plasma activity phenomena in the cosmos. The electron cyclotron maser (ECM) instability driven by FEBs trapped in magnetic fields can directly amplify radio wave radiations.

A Possible Metal-dominated Atmosphere below the Thick Aerosols of GJ 1214 b Suggested by Its JWST Panchromatic Transmission Spectrum

The Astrophysical Journal Letters
GJ 1214b is the archetype sub-Neptune for which thick aerosols have prevented us from constraining its atmospheric properties for over a decade. In this study, we leverage the panchromatic transmission spectrum of GJ 1214b established by the Hubble Space
