The First Hubble Detection of a Secondary Eclipse from a Rocky Exoplanet: the 5.4-hour planet TOI-2431 b
Sebastian Zieba, Billy Edwards, Samuel N. Quinn +18
We present an HST/WFC3 G141 phase-curve observation of the ultra-short-period rocky planet TOI-2431 b and detect its secondary eclipse in the near infrared. Combined with the TESS…
Sensitivity of Dry Lava Planet Atmospheric Emission Spectra to Changes in Lava Compositions
Christiaan P. A. van Buchem, Rojita Buddhacharya, Mantas Zilinskas +3
The atmospheres of hot rocky exoplanets are among the first primary targets of the JWST. Interpreting their atmospheric spectra requires understanding the link between silicate lav…
Hot and cloudy: High temperature clouds in super-Earths and sub-Neptunes
Leoni J. Janssen, Yamila Miguel, Michiel Min +3
JWST observations provide for the first time evidence for an atmosphere on a rocky exoplanet - 55 Cnc e. The atmosphere of 55 Cnc e is hot with K and sho…
Methane on the temperate exo-Saturn TOI-199b
Aaron Bello-Arufe, Renyu Hu, Mantas Zilinskas +10
Temperate ( K) gas giants represent an unexplored frontier in exoplanet atmospheric spectroscopy. Orbiting a G-type star every days, the Saturn-mass exopl…
Worlds Next Door: A Candidate Giant Planet Imaged in the Habitable Zone of Cen A. I. Observations, Orbital and Physical Properties, and Exozodi Upper Limits
Charles Beichman, Aniket Sanghi, Dimitri Mawet +27
We report on coronagraphic observations of the nearest solar-type star, Cen A, using the MIRI instrument on the James Webb Space Telescope. With three epochs of observation (Au…
Characterising the Atmosphere of 55 Cancri e: 1D Forward Model Grid for Current and Future JWST Observations
Mantas Zilinskas, Christiaan van Buchem, Sebastian Zieba +9
Recent JWST observations with NIRCam and MIRI of the ultra-short-period super-Earth 55 Cancri e indicate a possible volatile atmosphere surrounding the planet. Previous analysis of…
LavAtmos 2.0: Incorporating Volatiles Species in Vaporization Models
Christiaan P. A. van Buchem, Mantas Zilinskas, Yamila Miguel +1
Due to strong irradiation, hot rocky exoplanets are able to sustain lava oceans. Direct interaction between these oceans and overlying atmospheres can provide insight into planetar…
A secondary atmosphere on the rocky exoplanet 55 Cancri e
Renyu Hu, Aaron Bello-Arufe, Michael Zhang +14
Characterizing rocky exoplanets is a central endeavor of astronomy, and yet the search for atmospheres on rocky exoplanets has hitherto resulted in either tight upper limits on the…
Observability of silicates in volatile atmospheres of super-Earths and sub-Neptunes
Mantas Zilinskas, Yamila Miguel, Chritstiaan P. A. van Buchem +1
Many of the confirmed short period super-Earths and smaller sub-Neptunes are sufficiently irradiated for the surface silicates to be sustained in a long-lasting molten state. While…
LavAtmos: An open source chemical equilibrium vaporisation code for lava worlds
Christiaan P. A. Van Buchem, Yamila Miguel, Mantas Zilinskas +1
To date, over 500 short-period rocky planets with equilibrium temperatures above 1500 K have been discovered. Such planets are expected to support magma oceans, providing a direct…
K2 and Spitzer phase curves of the rocky ultra-short-period planet K2-141 b hint at a tenuous rock vapor atmosphere
S. Zieba, M. Zilinskas, L. Kreidberg +11
K2-141 b is a transiting, small (1.5 Re) ultra-short-period (USP) planet discovered by Kepler orbiting a K-dwarf host star every 6.7 hours. The planet's high surface temperature ma…
Observability of Evaporating Lava Worlds
Mantas Zilinskas, Christiaan van Buchem, Yamila Miguel +4
Lava worlds belong to a class of short orbital period planets reaching dayside temperatures high enough to melt their silicate crust. Theory predicts that the resulting lava oceans…
Ariel: Enabling planetary science across light-years
Giovanna Tinetti, Paul Eccleston, Carole Haswell +313
Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. Durin…
Temperature inversions on hot super-Earths: the case of CN in nitrogen-rich atmospheres
Mantas Zilinskas, Yamila Miguel, Yipeng Lyu +1
We show that in extremely irradiated atmospheres of hot super-Earths shortwave absorption of CN can cause strong temperature inversions. We base this study on previous observations…
Atmospheric compositions and observability of nitrogen dominated ultra-short period super-Earths
Mantas Zilinskas, Yamila Miguel, Paul Mollière +1
We explore the chemistry and observability of nitrogen dominated atmospheres for ultra-short-period super-Earths. We base the assumption, that super-Earths could have nitrogen fill…
