Observing a 542-day transiting giant with large TTVs: The 2025 transit of HIP 41378 f and new constraints on the outer system
Pietro Leonardi, Alexandre Santerne, Luca Borsato +27
Characterizing long-period transiting exoplanets is inherently challenging due to the rarity and long duration of transit events. Yet, these systems provide unique insights into pl…
RV and TTV Measurements of Two Transiting Long-Period Giants around TOI-4600
Tong Hu, Zitao Lin, Sharon X. Wang +27
TOI-4600b and c, originally identified by the Transiting Exoplanet Survey Satellite (TESS) and reported by I. Mireles et al. (2023), are a rare pair of transiting long-period giant…
KMT-2025-BLG-1616Lb: First Microlensing Bound Planet From DREAMS
Hongjing Yang, Weicheng Zang, Yoon-Hyun Ryu +60
We present observations and analysis of the bound planetary microlensing event KMT-2025-BLG-1616. The planetary signal was captured by the Korea Microlensing Telescope Network (KMT…
THYME XIII: Two young Neptunes orbiting a 75-Myr star in the Alpha Persei Cluster
Anne Dattilo, Andrew M. Vanderburg, Madyson G. Barber +28
Young planets with mass measurements are particularly valuable in studying atmospheric mass-loss processes, but these planets are rare and their masses difficult to measure due to…
The Polar Orbit of TOI-2374 b, a Planet in the Neptunian Ridge
Samuel W. Yee, Patrick Tamburo, Gudmundur Stefánsson +11
The ``Neptunian ridge'' is a recently identified peak in the frequency of planets with sizes between that of Neptune and Saturn orbiting their host stars with periods between 3 and…
A Ground-Based Transit Observation of the Long-Period Extremely Low-Density Planet HIP 41378 f
Juliana García-Mejía, Zoë L. de Beurs, Patrick Tamburo +25
We present a ground-based transit detection of HIP 41378 f, a long-period ( days), extremely low-density ( g cm) giant exoplanet in a dynamically com…
Spot-Crossing Variations Confirm a Misaligned Orbit for a Planet Transiting an M Dwarf
Patrick Tamburo, Samuel W. Yee, Juliana García-Mejía +4
TOI-3884~b is an unusual 6.4~R planet orbiting an M4 host, whose transits display large and persistent spot-crossing events. We used the \textit{Tierras} Observatory to mo…
The True Stellar Obliquity of a Sub-Saturn Planet from the Tierras Observatory and KPF
Patrick Tamburo, Samuel W. Yee, Juliana García-Mejía +7
We measure the true obliquity of TOI-2364, a K dwarf with a sub-Saturn-mass () transiting planet on the upper edge of the hot Neptune desert. We used new Rossiter-…
Multiple Patchy Cloud Layers in the Planetary Mass Object SIMP0136+0933
Allison M. McCarthy, Philip S. Muirhead, Patrick Tamburo +6
Multi-wavelength photometry of brown dwarfs and planetary-mass objects provides insight into their atmospheres and cloud layers. We present near-simultaneous and band mu…
Potential Atmospheric Compositions of TRAPPIST-1 c constrained by JWST/MIRI Observations at 15 m
Andrew P. Lincowski, Victoria S. Meadows, Sebastian Zieba +13
The first JWST observations of TRAPPIST-1 c showed a secondary eclipse depth of 421+/-94 ppm at 15 um, which is consistent with a bare rock surface or a thin, O2-dominated, low CO2…
No thick carbon dioxide atmosphere on the rocky exoplanet TRAPPIST-1 c
Sebastian Zieba, Laura Kreidberg, Elsa Ducrot +16
Seven rocky planets orbit the nearby dwarf star TRAPPIST-1, providing a unique opportunity to search for atmospheres on small planets outside the Solar System (Gillon et al., 2017)…
Predicting the Yield of Small Transiting Exoplanets around Mid-M and Ultra-Cool Dwarfs in the Nancy Grace Roman Space Telescope Galactic Bulge Time Domain Survey
Patrick Tamburo, Philip S. Muirhead, Courtney D. Dressing
We simulate the yield of small (0.5-4.0 R) transiting exoplanets around single mid-M and ultra-cool dwarfs (UCDs) in the Nancy Grace Roman Space Telescope Galactic Bulge T…
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.…
The Perkins INfrared Exosatellite Survey (PINES) I. Survey Overview, Reduction Pipeline, and Early Results
Patrick Tamburo, Philip S. Muirhead, Allison M. McCarthy +9
We describe the Perkins INfrared Exosatellite Survey (PINES), a near-infrared photometric search for short-period transiting planets and moons around a sample of 393 spectroscopica…
An Unusual Transmission Spectrum for the Sub-Saturn KELT-11b Suggestive of a Sub-Solar Water Abundance
Knicole D. Colón, Laura Kreidberg, Luis Welbanks +30
We present an optical-to-infrared transmission spectrum of the inflated sub-Saturn KELT-11b measured with the Transiting Exoplanet Survey Satellite (TESS), the Hubble Space Telesco…
Design Considerations for a Ground-Based Search for Transiting Planets around L and T Dwarfs
Patrick Tamburo, Philip S. Muirhead
We present design considerations for a ground-based survey for transiting exoplanets around L and T dwarfs, spectral classes that have yet to be thoroughly probed for planets. We s…
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…
