MARVEL Analysis of High‐Resolution Rovibrational Spectra of 16O13C18O

Journal of Computational Chemistry, Volume 46, Issue 1, January 5, 2025.
12348 measured transitions in the wavenumber range 578–9318 cm−1 for carbon dioxide (isotopologue 638) were used° to calculating 3975 empirical rovibrational energy levels with J° up to 82. ABSTRACT A large set of validated experimental transitions and empirical rovibrational energy levels are reported for the fifth most abundant carbon dioxide ...

Venus transit 2004: Illustrating the capability of exoplanet transmission spectroscopy

, 2011
The transit of Venus in 2004 offered the rare possibility to remotely sense a well-known planetary atmosphere using ground-based observations for absorption spectroscopy.

A Direct Comparison between the Use of Double Gray and Multiwavelength Radiative Transfer in a General Circulation Model with and without Radiatively Active Clouds

The Astrophysical Journal
Inhomogeneous cloud formation and wavelength-dependent phenomena are expected to shape hot Jupiter atmospheres. We present a general circulation model with multiwavelength “picket fence” radiative transfer and radiatively active, temperature-dependent ...

White Dwarf Stars in the Big Data Era

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT White dwarf stars are the most common endpoint of stellar evolution. Therefore, these old, numerous and compact objects provide valuable information on the late stages of stellar evolution, the physics of dense plasma and the structure and evolution of our Galaxy.

Ionospheric Conductances at the Giant Planets of the Solar System: A Comparative Study of Ionization Sources and the Impact of Meteoric Ions

Journal of Geophysical Research: Space Physics, Volume 130, Issue 1, January 2025.
Abstract The dynamics of giant planet magnetospheres is controlled by a complex interplay between their fast rotation, their interaction with the solar wind, and their diverse internal plasma and momentum sources. In the ionosphere, the Hall and Pedersen conductances are two key parameters that regulate the intensity of currents coupling the ...

Minimizing Star-spot Contamination of Exoplanet Transit Spectroscopy Using Alternate Normalization

The Astronomical Journal
Recently, M. H. Currie et al. (2023) simulated the detection of molecules in the atmospheres of temperate rocky exoplanets transiting nearby M-dwarf stars.

Saturns, but Not Super-Jupiters, Occur More Frequently in the Presence of Inner Super-Earths

The Astrophysical Journal
Studies from recent years have reached different conclusions regarding how frequently super-Earths are accompanied by long-period giant planets and vice versa. This relation has been predicted to be mass dependent by planet-formation models.

Astrometric detection of exoplanets from the ground

, 2013
Astrometry is a powerful technique to study the populations of extrasolar planets around nearby stars. It gives access to a unique parameter space and is therefore required for obtaining a comprehensive picture of the properties, abundances, and ...

What asteroseismology can do for exoplanets

, 2015
We describe three useful applications of asteroseismology in the context of exoplanet science: (1) the detailed characterisation of exoplanet host stars; (2) the measurement of stellar inclinations; and (3) the determination of orbital eccentricity from ...
