High-Resolution Transmission Spectra of Earth through Geological Time
Lisa Kaltenegger, Zifan Lin, Jack Madden
The next generation of ground- and space-based telescopes will be able to observe rocky Earth-like planets in the near future, transiting their host star. We explore how the transm…
High-resolution reflection spectra for Proxima b and Trappist-1e models for ELT observations
Zifan Lin, Lisa Kaltenegger
The closest stars that harbor potentially habitable planets are cool M-stars. Upcoming ground- and space-based telescopes will be able to search the atmosphere of such planets for…
Photometric analyses of Saturn's small moons: Aegaeon, Methone and Pallene are dark; Helene and Calypso are bright
M. M. Hedman, P. Helfenstein, R. O. Chancia +4
We examine the surface brightnesses of Saturn's smaller satellites using a photometric model that explicitly accounts for their elongated shapes and thus facilitates comparisons am…
The Gemini Planet Imager Exoplanet Survey: Dynamical Mass of the Exoplanet beta Pictoris b from Combined Direct Imaging and Astrometry
Eric L. Nielsen, Robert J. De Rosa, Jason J. Wang +51
We present new observations of the planet beta Pictoris b from 2018 with GPI, the first GPI observations following conjunction. Based on these new measurements, we perform a joint…
First Resolved Scattered-Light Images of Four Debris Disks in Scorpius-Centaurus with the Gemini Planet Imager
Justin Hom, Jennifer Patience, Thomas M. Esposito +57
We present the first spatially resolved scattered-light images of four debris disks around members of the Scorpius-Centaurus (Sco-Cen) OB Association with high-contrast imaging and…
Detecting and Characterizing Water Vapor in the Atmospheres of Earth Analogs through Observation of the 0.94 Micron Feature in Reflected Light
Adam J. R. W. Smith, Y. Katherina Feng, Jonathan J. Fortney +4
The characterization of rocky, Earth-like planets is an important goal for future large ground- and space-based telescopes. In support of developing an efficient observational stra…
Pulsed Disc Accretion Driven by Hot Jupiters
Jean Teyssandier, Dong Lai
We present 2D hydrodynamical simulations of hot Jupiters orbiting near the inner edge of protoplanetary discs. We systemically explore how the accretion rate at the inner disc edge…
How to Characterize Habitable Worlds and Signs of Life
L. Kaltenegger
The detection of exoplanets orbiting other stars has revolutionized our view of the cosmos. First results suggest that it is teeming with a fascinating diversity of rocky planets,…
ACCESS: A Visual to Near-infrared Spectrum of the Hot Jupiter WASP-43b with Evidence of , but no evidence of Na or K
Ian C. Weaver, Mercedes López-Morales, Néstor Espinoza +11
We present a new ground-based visual transmission spectrum of the hot Jupiter WASP-43b, obtained as part of the ACCESS Survey. The spectrum was derived from four transits observed…
Transmission Spectroscopy of WASP-79b from 0.6 to 5.0 m
Kristin S. Sotzen, Kevin B. Stevenson, David K. Sing +18
As part of the PanCET program, we have conducted a spectroscopic study of WASP-79b, an inflated hot Jupiter orbiting an F-type star in Eridanus with a period of 3.66 days. Building…
Detection of Na, K and HO in the hazy atmosphere of WASP-6b
Aarynn L. Carter, Nikolay Nikolov, David K. Sing +13
We present new observations of the transmission spectrum of the hot Jupiter WASP-6b both from the ground with the Very Large Telescope (VLT) FOcal Reducer and Spectrograph (FORS2)…
WASP-127b transmission spectrum]{Abundance measurements of HO and carbon-bearing species in the atmosphere of WASP-127b confirm its super-solar metallicity
Jessica J. Spake, David K. Sing, Hannah R. Wakeford +14
The chemical abundances of exoplanet atmospheres may provide valuable information about the bulk compositions, formation pathways, and evolutionary histories of planets. Exoplanets…
WASP-52b. The effect of starspot correction on atmospheric retrievals
Giovanni Bruno, Nikole K. Lewis, Munazza K. Alam +13
We perform atmospheric retrievals on the full optical to infrared () transmission spectrum of the inflated hot Jupiter WASP-52b by combining HST/STIS, WFC3 IR…
An updated visual orbit of the directly-imaged exoplanet 51 Eridani b and prospects for a dynamical mass measurement with Gaia
Robert J. De Rosa, Eric L. Nielsen, Jason J. Wang +52
We present a revision to the visual orbit of the young, directly-imaged exoplanet 51 Eridani b using four years of observations with the Gemini Planet Imager. The relative astromet…
A Hubble PanCET Study of HAT-P-11b: A Cloudy Neptune with a Low Atmospheric Metallicity
Yayaati Chachan, Heather A. Knutson, Peter Gao +14
We present the first comprehensive look at the m transmission spectrum of the warm ( K) Neptune HAT-P-11b derived from thirteen individual transits observed u…
Detection of ionized calcium in the atmosphere of the ultra-hot Jupiter KELT-9b
Jake D. Turner, Ernst J. W. de Mooij, Ray Jayawardhana +6
With a day-side temperature in excess of 4500K, comparable to a mid-K-type star, KELT-9b is the hottest planet known. Its extreme temperature makes KELT-9b a particularly interesti…
