A Candidate Innermost Fifth Planet In the HR 8799 System Revealed By JWST NIRISS Aperture Masking Interferometry
Jayke S. Nguyen, Louis Desdoigts, Alexandra Z. Greenbaum +20
We detect a candidate fifth planet in the HR 8799 system, directly imaged with the JWST/NIRISS Aperture Masking Interferometer (AMI). The detected source lies just above a con…
The Companions to B and A Stars Snapshot (C-BASS) Survey: I. Discovery of a Young Brown Dwarf Companion to HIP 17453
Marah Brinjikji, Adam J. Smith, Jennifer Patience +26
We report the detection of a new brown dwarf companion to HIP 17453 A, a chemically peculiar A0V star located at a distance of 81 pc. HIP 17453 A was observed with high-resolution…
HD 143811 AB b: A Directly Imaged Planet Orbiting a Spectroscopic Binary in Sco-Cen
Nathalie K. Jones, Jason J. Wang, Eric L. Nielsen +51
We present confirmation of HD 143811 AB b, a substellar companion to spectroscopic binary HD 143811 AB through direct imaging with the Gemini Planet Imager (GPI) and Keck NIRC2. HD…
Characterization of the Host Binary of the Directly Imaged Exoplanet HD 143811 AB b
Anne E. Peck, William Roberson, Eric L. Nielsen +50
HD~143811~AB is the host star to the directly imaged planet HD~143811~AB~b, which was recently discovered using data from the Gemini Planet Imager and Keck NIRC2. A member of the S…
Apache Point Observatory follow-up of ACcelerating Candidate ExopLanet host Stars (APO ACCELS): Ages for 166 Accelerating Stars in the Northern Hemisphere
Anne E. Peck, Eric L. Nielsen, Robert J. De Rosa +14
Directly imaged substellar companions with well-constrained ages and masses serve as vital empirical benchmarks for planet formation and evolution models. Potential benchmark compa…
Validation of elemental and isotopic abundances in late-M spectral types with the benchmark HIP 55507 AB system
Jerry W. Xuan, Jason J. Wang, Luke Finnerty +48
M dwarfs are common host stars to exoplanets but often lack atmospheric abundance measurements. Late-M dwarfs are also good analogs to the youngest substellar companions, which sha…
CD-27 11535: Evidence for a Triple System in the Pictoris Moving Group
Andrew D. Thomas, Eric L. Nielsen, Robert J. De Rosa +20
We present new spatially resolved astrometry and photometry of the CD-27 11535 system, a member of the Pictoris moving group consisting of two resolved K-type stars on a …
The Comprehensive Archive of Substellar and Planetary Accretion Rates
S. K. Betti, K. B. Follette, K. Ward-Duong +11
Accretion rates () of young stars show a strong correlation with object mass (); however, extension of the relation into the substellar regime is less certa…
Direct imaging discovery of a super-Jovian around the young Sun-like star AF Leporis
Robert J. De Rosa, Eric L. Nielsen, Zahed Wahhaj +5
(abridged) Expanding the sample of directly imaged companions to nearby, young stars that are amenable to detailed astrometric and spectroscopic studies is critical for the continu…
