TOI-6981 b: a transiting sub-Neptune at the water ice line

Madison G. Scott, Amaury H. M. J Triaud, Emily K. Pass +42

We present TOI-6981 b, a cold (Teq= 170.0 +/-4.5 K, assuming an Earth-like albedo) sub-Neptune (Rb=2.40+/-0.10 R_oplus) on a 60.8 day orbit around around its M4-type host star (R*=…

Post-perihelion Photometric and Spectroscopic Monitoring of the Interstellar Comet 3I/ATLAS

Goldy Ahuja, Shashikiran Ganesh, K. Aravind +12

The third interstellar object, comet 3I/ATLAS, was observed using various Indian telescopes during its post-perihelion evolution. We carried out imaging and spectroscopic observati…

IFU Observations of Comet 3I/ATLAS = C/2025 N1 (ATLAS) using the Hobby-Eberly Telescope with the VIRUS Instrument

Anita Cochran, Gregory Zeimann, Emmanuel Jehin +2

We observed interstellar object 3I/ATLAS = C/2025 N1 (ATLAS) on 9 December 2025 UT with the VIRUS spectrograph on the Hobby-Eberly Telescope. VIRUS is a low spectral resolving powe…

Assessing the Impact of High-Resolution Imaging on Statistical Validation of TESS Planet Candidates

Michael Collier, Steven Giacalone, Brian Derfer +38

High-resolution imaging is widely used to constrain false-positive scenarios in exoplanet validation, but it is a finite follow-up resource that reaches only a subset of candidates…

Unmasking (44) Nysa: Evidence for a trilobate structure

Kate Minker, Anthony Berdeu, Gianluca Li Causi +16

Context. (44) Nysa is one of the largest known E-type asteroids. Light curve inversion models have indicated that it may have an elongated shape commonly found in large binary syst…

Stellar Multiplicity of M Dwarfs with Short-period Giant Planets, and the Characterization of TOI-5628Ab

Tianjun Gan, Alexandrine L'Heureux, Charles Cadieux +33

Binary stars are ubiquitous, yet it remains unclear how wide-orbit stellar companions influence the formation of hot Jupiters, particularly around M dwarfs. Here, we first report t…
