Conspicuous Gas, Cryptic Dust: Spectroscopy and Chromaticity of Complex Periodic Variables
Luke G. Bouma, Facundo Perez Paolino, Lynne A. Hillenbrand +17
Complex periodic variables (CPVs) are young low-mass stars whose light curves show periodic dips indicative of transiting corotating material. The origin and composition of this ma…
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…
A Minute-Cadence Deep Bulge Survey: First Data Release of DREAMS
Hongjing Yang, Weicheng Zang, Francisco Valdes +31
The DECam Rogue Earths and Mars Survey (DREAMS), a NOIRLab survey program, has been conducting a three-year survey covering a 5 deg area in the Galactic bulge (roughly spanning…
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…
