The metal-poor atmosphere of a Neptune/Sub-Neptune planet progenitor
Saugata Barat, Jean-Michel Désert, Allona Vazan +12
Young transiting exoplanets offer a unique opportunity to characterize the atmospheres of fresh and evolving products of planet formation. We present the transmission spectrum of V…
A Near-infrared Variability Survey of Young Planetary-mass Objects
Pengyu Liu, Beth A. Biller, Johanna M. Vos +12
We present a photometric variability survey of young planetary-mass objects using the New Technology Telescope in the Js and Ks bands. Surface gravity plays an important role in th…
Chaotic Type I Migration in Turbulent Discs
Yinhao Wu, Yi-Xian Chen, Douglas N. C. Lin
By performing global hydrodynamical simulations of accretion discs with driven turbulence models, we demonstrate that elevated levels of turbulence induce highly stochastic migrati…
Constraining Background N2 Inventories on Directly Imaged Terrestrial Exoplanets to Rule Out O2 False Positives
Sawyer Hall, Joshua Krissansen-Totton, Tyler Robinson +2
Direct imaging spectroscopy with future space-based telescopes will constrain terrestrial planet atmospheric composition and potentially detect biosignature gases. One promising in…
Giant Outer Transiting Exoplanet Mass (GOT 'EM) Survey: III. Recovery and Confirmation of a Temperate, Mildly Eccentric, Single-Transit Jupiter Orbiting TOI-2010
Christopher R. Mann, Paul A. Dalba, David Lafrenière +48
Large-scale exoplanet surveys like the TESS mission are powerful tools for discovering large numbers of exoplanet candidates. Single-transit events are commonplace within the resul…
A Pathway for Collisional Planetesimal Growth in the Ice-Dominant Regions of Protoplanetary Disks
Elizabeth Yunerman, Diana Powell, Ruth Murray-Clay
We present a semi-analytic model for the growth, drift, desorption, and fragmentation of millimeter- to meter-sized particles in protoplanetary disks. Fragmentation occurs where pa…
TOI-1801 b: A temperate mini-Neptune around a young M0.5 dwarf
M. Mallorquín, E. Goffo, E. Pallé +79
We report the discovery, mass, and radius determination of TOI-1801 b, a temperate mini-Neptune around a young M dwarf. TOI-1801 b was observed in TESS sectors 22 and 49, and the a…
Kilometer-precise (UII) Umbriel physical properties from the multichord stellar occultation on 2020 September 21
M. Assafin, S. Santos-Filho, B. E. Morgado +39
We report the results of the stellar occultation by (UII) Umbriel on September 21st, 2020. The shadow crossed the USA and Canada, and 19 positive chords were obtained. A limb param…
Outgassing Composition of the Murchison Meteorite: Implications for Volatile Depletion of Planetesimals and Interior-atmosphere Connections for Terrestrial Exoplanets
Maggie A. Thompson, Myriam Telus, Graham Harper Edwards +5
Outgassing is a central process during the formation and evolution of terrestrial planets and their atmospheres both within and beyond the solar system. Although terrestrial planet…
Using Lyman- transits to constrain models of atmospheric escape
Ethan Schreyer, James. E. Owen, R. O. Parke Loyd +1
Lyman- transits provide an opportunity to test models of atmospheric escape directly. However, translating observations into constraints on the properties of the escaping atmosp…
Global Chemical Transport on Hot Jupiters: Insights from 2D VULCAN photochemical model
Shang-Min Tsai, Vivien Parmentier, João M. Mendonça +7
The atmospheric dynamics of tidally-locked hot Jupiters is characterized by strong equatorial winds. Understanding the interaction between global circulation and chemistry is cruci…
A roadmap for the atmospheric characterization of terrestrial exoplanets with JWST
TRAPPIST-1 JWST Community Initiative, :, Julien de Wit +80
Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominen…
Clouds and Clarity: Revisiting Atmospheric Feature Trends in Neptune-size Exoplanets
Jonathan Brande, Ian J. M. Crossfield, Laura Kreidberg +12
Over the last decade, precise exoplanet transmission spectroscopy has revealed the atmospheres of dozens of exoplanets, driven largely by observatories like the Hubble Space Telesc…
Water absorption in the transmission spectrum of the water-world candidate GJ9827d
Pierre-Alexis Roy, Björn Benneke, Caroline Piaulet +16
Recent work on the characterization of small exoplanets has allowed us to accumulate growing evidence that the sub-Neptunes with radii greater than often host H…
Revised orbits of the two nearest Jupiters
Fabo Feng, R. Paul Butler, Steven S. Vogt +2
With its near-to-mid-infrared high contrast imaging capabilities, JWST is ushering us into a golden age of directly imaging Jupiter-like planets. As the two closest cold Jupiters,…
Tidal Response and Shape of Hot Jupiters
Sean M. Wahl, Daniel Thorngren, Tiger Lu +1
We study the response of hot Jupiters to a static tidal perturbation using the Concentric MacLaurin Spheroid (CMS) method. For strongly irradiated planets, we first performed radia…
Constraints on sub-terrestrial free-floating planets from Subaru microlensing observations
William DeRocco, Nolan Smyth, Stefano Profumo
The abundance of protoplanetary bodies ejected from their parent star system is presently poorly-constrained. With only two existing optical observations of interstellar objects in…
Chasing rainbows and ocean glints: Inner working angle constraints for the Habitable Worlds Observatory
Sophia R. Vaughan, Timothy D. Gebhard, Kimberly Bott +41
NASA is engaged in planning for a Habitable Worlds Observatory (HabWorlds), a coronagraphic space mission to detect rocky planets in habitable zones and establish their habitabilit…
TESS discovery of a super-Earth orbiting the M dwarf star TOI-1680
M. Ghachoui, A. Soubkiou, R. D. Wells +52
We report the discovery by the TESS mission of a super-Earth on a 4.8-d orbit around an inactive M4.5 dwarf (TOI-1680) validated by ground-based facilities. The host star is locate…
Systematic Multi-Epoch Monitoring of LkCa 15: Dynamic Dust Structures on Solar-System Scales
