The Diversity of Cold Worlds: Age and Characterization of the Exoplanet COCONUTS-2b
Rocio Kiman, Charles A. Beichman, Azul Ruiz Diaz +19
Studying cold brown dwarfs is key to understanding the diverse characteristics of cold giant exoplanets atmospheres. COCONUTS-2, is a wide binary system composed of a T9 brown dwar…
JWST Coronagraphic Images of 14 Her c: a Cold Giant Planet in a Dynamically Hot, Multi-planet System
Daniella C. Bardalez Gagliuffi, William O. Balmer, Laurent Pueyo +16
Most observed multi-planet systems are coplanar, in a dynamically "cold" configuration of concentric orbits like our own Solar System. With the James Webb Space Telescope (JWST) we…
Diversity of Cold Worlds: A Near Complete Spectral Energy Distribution for 2MASS J04151954-0935066 using JWST
Sherelyn Alejandro Merchan, Jacqueline K. Faherty, Genaro Suárez +25
We present the a near complete spectral energy distribution (SED) for an extrasolar world: the T8 brown dwarf 2MASS~J041519540935066. Spanning from optical to mid-infrared (0.7-…
The Y Dwarf Population with HST: unlocking the secrets of our coolest neighbours -- II. Parallaxes and Proper Motions
Clémence Fontanive, Luigi R. Bedin, Loïc Albert +1
We present astrometric results from a Hubble Space Telescope (HST) campaign aimed at determining precise distances for cold Y-type brown dwarfs. Combining observations from a dedic…
SCExAO/CHARIS Spectroscopic Characterization of Cloudy L/T Transition Companion Brown Dwarf HIP 93398 B
Briley Lewis, Yiting Li, Aidan Gibbs +10
Brown dwarfs with measured dynamical masses and spectra from direct imaging are benchmarks that anchor substellar atmosphere cooling and evolution models. We present Subaru SCExAO/…
The Perkins INfrared Exosatellite Survey (PINES) II. Transit Candidates and Implications for Planet Occurrence around L and T Dwarfs
Patrick Tamburo, Philip S. Muirhead, Allison M. McCarthy +7
We describe a new transit detection algorithm designed to detect single transit events in discontinuous Perkins INfrared Exosatellite Survey (PINES) observations of L and T dwarfs.…
14 Her: a likely case of planet-planet scattering
Daniella C. Bardalez Gagliuffi, Jacqueline K. Faherty, Yiting Li +4
In this Letter, we measure the full orbital architecture of the two-planet system around the nearby K0 dwarf 14 Herculis. 14 Her (HD 145675, HIP 79248) is a middle-aged ($4.6^{+3.8…
Individual Dynamical Masses of DENIS J063001.4184014AB Reveal A Likely Young Brown Dwarf Triple
Johannes Sahlmann, Trent J. Dupuy, Adam J. Burgasser +6
The binary nature of the M8.5 dwarf DENIS J063001.4184014AB (DE063018) was discovered with astrometric monitoring from the ground, which determined the unresolved photocentri…
WISE J135501.90-825838.9 is a Nearby, Young, Extremely Low-mass Substellar Binary
C. A. Theissen, D. C. Bardalez Gagliuffi, J. K. Faherty +2
We present a parallax solution for WISE J135501.90-825838.9, a spectral binary with spectral types L7+T7.5 and candidate AB Doradus member. Using astrometry, we obtain a dis…
Searching for Exosatellites Orbiting L and T Dwarfs: Connecting Planet Formation to Moon Formation and Finding New Temperate Worlds
Philip S. Muirhead, Julie N. Skinner, Jacqueline Radigan +7
L-type and T-type dwarfs span the boundaries between main-sequence stars, brown dwarfs, and planetary-mass objects. For these reasons, L and T dwarfs are the perfect laboratories f…
Brown Dwarfs and Directly Imaged Exoplanets in Young Associations
Jacqueline K. Faherty, Katelyn Allers, Daniella Bardalez Gagliuffi +7
In order to understand the atmospheres as well as the formation mechanism of giant planets formed outside our solar system, the next decade will require an investment in studies of…
Identification of WISE J000100.45+065259.6 as an M8.5+T5 Spectral Binary Candidate
Adam J. Burgasser, Christopher A. Theissen, Daniella C. Bardalez Gagliuffi +1
[not part of RNAAS note] We report the discovery of WISE J000100.45+065259.6 as a very low mass star/brown dwarf spectral binary candidate, on the basis of low resolution near-infr…
Temperate Earth-sized planets transiting a nearby ultracool dwarf star
Michael Gillon, Emmanuel Jehin, Susan M. Lederer +12
Star-like objects with effective temperatures of less than 2,700 kelvin are referred to as ultracool dwarfs. This heterogeneous group includes stars of extremely low mass as well a…
