Benchmark Brown Dwarf Systems I: Chemical Abundance Analysis of FGK Stars with Wide-Separation Brown Dwarf Companions Using PEPSI
Caprice L. Phillips, Megan Bedell, Catherine Manea +11
The authors performed a high‑resolution spectroscopic survey of 32 FGK stars that host wide‑separation brown dwarf companions, deriving precise stellar parameters and abundances fo…
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). 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 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…
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…
