Modeling the Dynamics and Thermochemistry for the Outer Atmospheres of the Ultra-hot Jupiter WASP-121b
Lile Wang, Yiren Lin, Ji Wang +1
We present three-dimensional simulations of the ultra-hot Jupiter (UHJ) WASP-121b from the planetary surface to extended outflows, coupling hydrodynamics with consistent non-equili…
Surveying Ultra-hot Jupiters using Phase Curves with
Kaz Gary, Ji Wang, Anusha Pai Asnodkar +1
Due to their high equilibrium temperatures ( 2000 K), ultra-hot Jupiters (UHJs) are the best characterized exoplanets to date. However, many questions about their forma…
PEPSI Investigation, Retrieval, and Atlas of Numerous Giant Atmospheres (PIRANGA). IV. High-Resolution Phased-Resolved Spectroscopy of The Ultra Hot Jupiter KELT-20 b
Victoria Bonidie, Marshall C. Johnson, Ji Wang +7
We present five datasets of high-resolution optical emission spectra of the ultra-hot Jupiter KELT-20 b with the PEPSI spectrograph. Using a Bayesian retrieval framework, we constr…
Kepler's Platonic Model and Its Application to Exoplanetary Systems
Ji Wang
Johannes Kepler's attempt to explain the arrangement of the six innermost planets of the Solar System using his Platonic Solid Model-which postulates that planetary orbits are nest…
PEPSI Investigation, Retrieval, and Atlas of Numerous Giant Atmospheres (PIRANGA). III. Composition and winds in the atmosphere of TOI-1518 b
Connor Basinger, Marshall C. Johnson, Ji Wang +6
Ultra-hot Jupiters (UHJs) orbit close to their host stars and experience extreme conditions, making them important laboratories to explore atmospheric composition and dynamics. Tra…
PEPSI Investigation, Retrieval, and Atlas of Numerous Giant Atmospheres (PIRANGA). II. Phase-Resolved Cross-Correlation Transmission Spectroscopy of KELT-20b
Calder Lenhart, Marshall C. Johnson, Ji Wang +5
KELT-20b is a well-studied ( K) ultra hot Jupiter, but its multidimensional atmospheric structure remains unconstrained. We performed high-resolution cross-corr…
PEPSI's non-detection of escaping hydrogen and metal lines adds to the enigma of WASP-12 b
Anusha Pai Asnodkar, Ji Wang, Madelyn Broome +5
WASP-12 b is an ultra-hot Jupiter (UHJ) of special interest for atmospheric studies since it is on an inspiraling orbit in an extreme environment of intense radiation and circumste…
PEPSI Investigation, Retrieval, and Atlas of Numerous Giant Atmospheres (PIRANGA). I. The Ubiquity of Fe I Emission and Inversions in Ultra Hot Jupiter Atmospheres
Sydney Petz, Marshall C. Johnson, Anusha Pai Asnodkar +4
We present high-resolution optical emission spectroscopy observations of the ultra hot Jupiters (UHJs) TOI-1431 b and TOI-1518 b using the PEPSI spectrograph on the LBT. We detect…
Atmospheric Waves Driving Variability and Cloud Modulation on a Planetary-Mass Object
Michael K. Plummer, Ji Wang, Étienne Artigau +2
Planetary-mass objects and brown dwarfs at the transition (\,K) from relatively red L dwarfs to bluer mid-T dwarfs show enhanced spectrophotometric variabilit…
Detecting Biosignatures in Nearby Rocky Exoplanets using High-Contrast Imaging and Medium-Resolution Spectroscopy with Extremely Large Telescope
Huihao Zhang, Ji Wang, Michael K. Plummer
In the upcoming decades, one of the primary objectives in exoplanet science is to search for habitable planets and signs of extraterrestrial life in the universe. Signs of life can…
The PEPSI Exoplanet Transit Survey (PETS) IV: Assessing the atmospheric chemistry of KELT-20b
Sydney Petz, Marshall C. Johnson, Anusha Pai Asnodkar +11
Most ultra hot Jupiters (UHJs) show evidence of temperature inversions, in which temperature increases with altitude over a range of pressures. Temperature inversions can occur whe…
Fizzy Super-Earths: Impacts of Magma Composition on the Bulk Density and Structure of Lava Worlds
Kiersten M. Boley, Wendy R. Panero, Cayman T. Unterborn +3
Lava worlds are a potential emerging population of Super-Earths that are on close-in orbits around their host stars with likely partially molten mantles. To date, few studies addre…
Mapping the Skies of Ultracool Worlds: Detecting Storms and Spots with Extremely Large Telescopes
Michael K. Plummer, Ji Wang
Extremely large telescopes (ELTs) present an unparalleled opportunity to study the magnetism, atmospheric dynamics, and chemistry of very low mass stars (VLMs), brown dwarfs, and e…
