Rotational broadening of exoplanet spectra in arbitrarily oriented systems: Application to reflected light
Sophia R. Vaughan, Laura Kreidberg
Exoplanet reflection spectra contain a wealth of information, which we are now beginning to access. At a high spectral resolution, the rotation of both the star and the planet affe…
The Barnard's Star Planetary System: Stability, Composition, and Evolution of Four Sub-Earth Exoplanets
Xander Byrne, Claire Marie Guimond, Amy Bonsor +3
Barnard's Star is the nearest single star to the Sun (1.8 pc), and hosts four recently-discovered planets. The star also has well-characterized stellar abundances of important rock…
The panchromatic JWST dayside spectrum of WASP-121 b reveals a refractory-rich formation
K. Angelique Kahle, Paul Mollière, Laura Kreidberg +16
One path to understand how planets form is to link their present-day atmospheric composition to predictions from planet formation models. For the hottest planets, the abundances of…
The CRIMSON survey I: super-stellar SiO in the directly imaged companion TWA 5 B from high-resolution M-band spectroscopy
Luke T. Parker, Jayne L. Birkby, Siddharth Gandhi +4
Silicon is a key refractory element in giant planet atmospheres, which governs the formation of magnesium-silicate clouds, and reflects the quantity of silicates accreted during fo…
No TiO detected in the hot Neptune-desert planet LTT-9779 b in reflected light at high spectral resolution
Sophia R. Vaughan, Jayne L. Birkby, Natasha E. Batalha +12
LTT-9779 b is an inhabitant of the hot Neptune desert and one of only a few planets with a measured high albedo. Characterising the atmosphere of this world is the key to understan…
Limits on the atmospheric metallicity and aerosols of the sub-Neptune GJ 3090 b from high-resolution CRIRES+ spectroscopy
Luke T. Parker, João M. Mendonça, Hannah Diamond-Lowe +9
The sub-Neptune planets have no solar system analogues, and their low bulk densities suggest thick atmospheres containing degenerate quantities of volatiles and H/He, surrounding c…
Into the red: an M-band study of the chemistry and rotation of Pictoris b at high spectral resolution
Luke T. Parker, Jayne L. Birkby, Rico Landman +7
High-resolution cross-correlation spectroscopy (HRCCS) combined with adaptive optics has been enormously successful in advancing our knowledge of exoplanet atmospheres, from chemis…
ELEPHANT: ExtragaLactic alErt Pipeline for Hostless AstroNomical Transients
P. J. Pessi, R. Durgesh, L. Nakazono +11
Context. Transient astronomical events that exhibit no discernible association with a host galaxy are commonly referred to as hostless. These rare phenomena are associated with ext…
Behind the Mask: can HARMONI@ELT detect biosignatures in the reflected light of Proxima b?
Sophia R. Vaughan, Jayne L. Birkby, Niranjan Thatte +7
Proxima b is a rocky exoplanet in the habitable zone of the nearest star system and a key test case in the search for extraterrestrial life. Here, we investigate the characterizati…
Integrated photonic-based coronagraphic systems for future space telescopes
Niyati Desai, Lorenzo König, Emiel Por +38
The detection and characterization of Earth-like exoplanets around Sun-like stars is a primary science motivation for the Habitable Worlds Observatory. However, the current best te…
Visible extreme adaptive optics on extremely large telescopes: Towards detecting oxygen in Proxima Centauri b and analogs
J. Fowler, Sebastiaan Y. Haffert, Maaike A. M. van Kooten +38
Looking to the future of exo-Earth imaging from the ground, core technology developments are required in visible extreme adaptive optics (ExAO) to enable the observation of atmosph…
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…
Planet Hunters TESS II: Findings from the first two years of TESS
Nora L. Eisner, Oscar Barragán, Chris Lintott +23
We present the results from the first two years of the Planet Hunters TESS citizen science project, which identifies planet candidates in the TESS data by engaging members of the g…
