WASP-107b's density is even lower: a case study for the physics of planetary gas envelope accretion and orbital migration
Caroline Piaulet, Björn Benneke, Ryan A. Rubenzahl +21
With a mass in the Neptune regime and a radius of Jupiter, WASP-107b presents a challenge to planet formation theories. Meanwhile, the planet's low surface gravity and the star's b…
Transmission spectroscopy for the warm sub-Neptune HD3167c: evidence for molecular absorption and a possible high metallicity atmosphere
Thomas Mikal-Evans, Ian J. M. Crossfield, Bjorn Benneke +26
We present a transmission spectrum for the warm (500-600K) sub-Neptune HD3167c obtained using the Hubble Space Telescope Wide Field Camera 3 infrared spectrograph. We combine these…

S. Dreizler, I., J. +134
We report the discovery of a Neptune-like planet (LP 714-47 b, P = 4.05204 d, m_b = 30.8 +/- 1.5 M_earth , R_b = 4.7 +/- 0.3 R_earth ) located in the 'hot Neptune desert'. Confirma…
Phase Curves of Hot Neptune LTT 9779b Suggest a High-Metallicity Atmosphere
Ian J. M. Crossfield, Diana Dragomir, Nicolas B. Cowan +20
Phase curve measurements provide a global view of the composition, thermal structure, and dynamics of exoplanet atmospheres. Although most of the dozens of phase curve measurements…
Spitzer Reveals Evidence of Molecular Absorption in the Atmosphere of the Hot Neptune LTT 9979b
Diana Dragomir, Ian J. M. Crossfield, Bjorn Benneke +27
Non-rocky sub-jovian exoplanets in high irradiation environments are rare. LTT 9979b, also known as TESS Object of Interest (TOI) 193.01, is one of the few such planets discovered…
Direct confirmation of the radial-velocity planet Pic c
M. Nowak, S. Lacour, A. -M. Lagrange +90
Methods used to detect giant exoplanets can be broadly divided into two categories: indirect and direct. Indirect methods are more sensitive to planets with a small orbital period,…
A Comprehensive Reanalysis of 's 4.5 m Phase Curves, and the Phase Variations of the Ultra-hot Jupiters MASCARA-1b and KELT-16b
Taylor J. Bell, Lisa Dang, Nicolas B. Cowan +12
We have developed an open-source pipeline for the analysis of \textit{Spitzer}/IRAC channel 1 and 2 time-series photometry, incorporating some of the most popular decorrelation met…
An astronomical institute's perspective on meeting the challenges of the climate crisis
Knud Jahnke, Christian Fendt, Morgan Fouesneau +10
Analysing greenhouse gas emissions of an astronomical institute is a first step in reducing its environmental impact. Here, we break down the emissions of the Max Planck Institute…
A Giant Planet Candidate Transiting a White Dwarf
Andrew Vanderburg, Saul A. Rappaport, Siyi Xu +61
Astronomers have discovered thousands of planets outside the solar system, most of which orbit stars that will eventually evolve into red giants and then into white dwarfs. During…
TOI-824 b: A New Planet on the Lower Edge of the Hot Neptune Desert
Jennifer A. Burt, Louise D. Nielsen, Samuel N. Quinn +54
We report the detection of a transiting hot Neptune exoplanet orbiting TOI-824 (SCR J1448-5735), a nearby (d = 64 pc) K4V star, using data from the \textit{Transiting Exoplanet Sur…
Physical Parameters of the Multi-Planet Systems HD 106315 and GJ 9827
Molly R. Kosiarek, David A. Berardo, Ian J. M. Crossfield +42
HD 106315 and GJ 9827 are two bright, nearby stars that host multiple super-Earths and sub-Neptunes discovered by K2 that are well suited for atmospheric characterization. We refin…
Exogeoscience and Its Role in Characterizing Exoplanet Habitability and the Detectability of Life
Cayman T. Unterborn, Paul K. Byrne, Ariel D. Anbar +24
The search for exoplanetary life must encompass the complex geological processes reflected in an exoplanet's atmosphere, or we risk reporting false positive and false negative dete…
Retrieving scattering clouds and disequilibrium chemistry in the atmosphere of HR 8799e
P. Mollière, T. Stolker, S. Lacour +25
Clouds are ubiquitous in exoplanet atmospheres and represent a challenge for the model interpretation of their spectra. Complex cloud models are too numerically costly for generati…
Tentative Evidence for Water Vapor in the Atmosphere of the Neptune-Size Exoplanet HD 106315 c
