A Pair of Warm Saturn-mass Planets near the 2:1 Mean Motion Resonance around TOI-3850
Sean Collins, Michelle Kunimoto, Nicolas B. Cowan +24
Warm Jupiters, with orbital periods of -- and radii exceeding , are a relatively understudied class of exoplanets occupying the parameter space bet…
Spectroscopic follow-up of compact object binary candidates from Gaia DR3: White dwarfs, neutron stars, black holes, and the parallax zeropoint
Kareem El-Badry, David W. Latham, Hans-Walter Rix +12
Astrometry and radial velocities (RVs) from Gaia DR3 yielded orbits for hundreds of thousands of binary systems, including several samples proposed to contain black holes (BHs), ne…
HIP 61637 b: a TESS Brown Dwarf in a Near-circular Orbit around a Massive A-type Star
Nino Ephremidze, David W. Latham, Perry Berlind +8
We present the characterization of HIP 61637 b (TOI-5401 b), a brown dwarf discovered by TESS to transit an A-type star. HIP 61637 is the most massive and the brightest star known…
CAFE follow-up of TESS hot Jupiter candidates left behind: I. Five newly confirmed planets and a false positive
J. Lillo-Box, C. Cifuentes, O. Balsalobre-Ruza +56
Hot Jupiters are key targets for understanding planet formation, migration, and atmospheres. Yet, most ground-based follow-up resources for the TESS mission are focused on confirmi…
The Occurrence Rate of Nearby Planetary Companions to Hot Jupiters
Lizhou Sha, Andrew M. Vanderburg, Chelsea X. Huang +33
The paper measures how often hot Jupiters have nearby transiting companion planets using TESS data, finding an occurrence rate of about 8%, which informs theories of hot‑Jupiter fo…
TOI-7169 b: A Hot Jupiter Transiting a Metal-Poor Star
Joshua D. Simon, Joseph E. Rodriguez, Jhon Yana Galarza +38
Most known planets are found around metal-rich host stars, which has made it difficult to determine whether a lower metallicity limit for planet formation exists and how the proper…
