The Effects of Irradiation on Hot Jovian Atmospheres: Heat Redistribution and Energy Dissipation

, 2012
Hot Jupiters, due to the proximity to their parent stars, are subjected to a strong irradiating flux which governs their radiative and dynamical properties.

The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

A Metal-poor Atmosphere with a Hot Interior for a Young Sub-Neptune Progenitor: JWST/NIRSpec Transmission Spectrum of V1298 Tau b

The Astronomical Journal
We present the JWST/NIRSpec G395H transmission spectrum of the young (10–30 Myr) transiting planet V1298 Tau b (9.85 ± 0.35 R _⊕ , T _eq  = 670 K). Combined Hubble Space Telescope and JWST observations reveal a haze-free, H/He-dominated atmosphere with a

Effects of Hydrogen on Fe‐S Alloys and Their Implications for the Martian Core

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Meteorites suggest the Martian core comprises iron (Fe) or iron‐nickel (Fe‐Ni) alloy with sulfur (S) identified as the primary light element. The InSight data revealed a larger, less dense Martian core than previously estimated, indicating additional light elements.

Exoplanet Occurrence Rate with Age for FGK Stars in Kepler

The Astronomical Journal
We measure the exoplanet occurrence rate as a function of isochrone and gyrochronology ages using confirmed and candidate planets identified in Q1–17 DR25 Kepler data. We employ Kepler's pipeline detection efficiency to correct for the expected number of

Towards consistent mapping of distant worlds: secondary-eclipse scanning of the exoplanet HD189733b

, 2012
Mapping distant worlds is the next frontier for exoplanet infrared photometry studies. Ultimately, constraining spatial and temporal properties of an exoplanet atmosphere will provide further insight into its physics. For tidally-locked hot Jupiters that

Magnetic Evolution of Super‐Earth Exoplanets With a Basal Magma Ocean

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Habitability of super‐Earths likely requires self‐sustained magnetic fields to shield their atmospheres from stellar forcing. Extreme pressures and temperatures probably produce a long‐lived basal magma ocean (BMO), a potential source for these fields.

The transiting exoplanet CoRoT-11b and its peculiar tidal evolution [PDF]

EPJ Web of Conferences, 2011
CoRoT-11b is a fairly massive hot-Jupiter (Mp = 2.33 ± 0.34 MJup ) in a 3 days orbit around a F6 V star with an age of 2 ± 1 Gyr. The relatively high projected rotational velocity of the star (v sin i⋆ = 40 ± 5 km/s) places CoRoT-11 among the most rapidly rotating planet hosting stars discovered so far.

Conclusive Evidence for a Population of Water Worlds around M Dwarfs Remains Elusive

The Astrophysical Journal Letters, 2023
The population of small, close-in exoplanets is bifurcated into super-Earths and sub-Neptunes. We calculate physically motivated mass–radius relations for sub-Neptunes, with rocky cores and H/He-dominated atmospheres, accounting for their thermal ...
