[HTML][HTML] From thermal dissociation to condensation in the atmospheres of ultra hot Jupiters: WASP-121b in context

V Parmentier, MR Line, JL Bean, M Mansfield… - Astronomy & …, 2018 - aanda.org
Context. A new class of exoplanets has emerged: the ultra hot Jupiters, the hottest close-in
gas giants. The majority of them have weaker-than-expected spectral features in the 1.1− 1.7 …

Aerosols in exoplanet atmospheres

P Gao, HR Wakeford, SE Moran, V Parmentier - 2021 - Wiley Online Library
Observations of exoplanet atmospheres have shown that aerosols, like in the solar system,
are common across a variety of temperatures and planet types. The formation and …

The atmospheric circulation of ultra-hot Jupiters

X Tan, TD Komacek - The Astrophysical Journal, 2019 - iopscience.iop.org
Recent observations of ultra-hot Jupiters with dayside temperatures in excess of 2500 K
have found evidence for new physical processes at play in their atmospheres. In this work …

Is the Atmosphere of the Ultra-hot Jupiter WASP-121 b Variable?

Q Changeat, JW Skinner, JYK Cho… - The Astrophysical …, 2024 - iopscience.iop.org
We present a comprehensive analysis of the Hubble Space Telescope observations of the
atmosphere of WASP-121 b, an ultra-hot Jupiter. After reducing the transit, eclipse, and …

Using transfer learning to detect galaxy mergers

S Ackermann, K Schawinski, C Zhang… - Monthly Notices of …, 2018 - academic.oup.com
We investigate the use of deep convolutional neural networks (deep CNNs) for automatic
visual detection of galaxy mergers. Moreover, we investigate the use of transfer learning in …

Exploring the effects of active magnetic drag in a general circulation model of the ultrahot Jupiter WASP-76b

H Beltz, E Rauscher, MT Roman… - The Astronomical …, 2021 - iopscience.iop.org
Ultrahot Jupiters represent an exciting avenue for testing extreme physics and observing
atmospheric circulation regimes not found in our solar system. Their high temperatures …

Climate of an ultra hot Jupiter-Spectroscopic phase curve of WASP-18b with HST/WFC3

J Arcangeli, JM Désert, V Parmentier… - Astronomy & …, 2019 - aanda.org
We present the analysis of a full-orbit, spectroscopic phase curve of the ultra hot Jupiter
(UHJ) WASP-18b, obtained with the Wide Field Camera 3 aboard the Hubble Space …

Strong biases in retrieved atmospheric composition caused by day–night chemical heterogeneities

W Pluriel, T Zingales, J Leconte… - Astronomy & …, 2020 - aanda.org
Most planets currently amenable to transit spectroscopy are close enough to their host stars
to exhibit a relatively strong day to night temperature gradient. For hot planets this leads to a …

A transition between the hot and the ultra-hot Jupiter atmospheres

C Baxter, JM Désert, V Parmentier, M Line… - Astronomy & …, 2020 - aanda.org
A key hypothesis in the field of exoplanet atmospheres is the trend of atmospheric thermal
structure with planetary equilibrium temperature. We explore this trend and report here the …

Statistical characterization of hot Jupiter atmospheres using Spitzer's secondary eclipses

E Garhart, D Deming, A Mandell… - The Astronomical …, 2020 - iopscience.iop.org
We report 78 secondary eclipse depths for a sample of 36 transiting hot Jupiters observed at
3.6 and 4.5 μm using the Spitzer Space Telescope. Our eclipse results for 27 of these …
