Low-cost neural summaries for cosmological inference: an ensemble of convolutional neural networks trained on approximate simulations

Iñigo Sáez-Casares, Davide Bianchi, Matteo Calabrese +1

Machine learning can build near-optimal summary statistics for extracting cosmological information from the large-scale structure of the Universe. Training them, however, requires…

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= 175^{+6}_{-5} K, assuming an Earth-like albedo) sub-Neptune (Rb=2.51+/-0.11 R_oplus) orbiting on a 60.8 day orbit around around its M4-type host…

Astra: an open-source fully autonomous robotic observatory control software

Peter P. Pedersen, David Degen, Lionel Garcia +12

Robotic and autonomous observatories are critical for modern time-domain and high-cadence astronomical surveys. The operation of these facilities requires complex software coordina…

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…

A Previously Underexplored Regime in TESS: Minute-Scale Eclipses Reveal Ten White Dwarf-Cool M-Dwarf Binaries

Tristan Cavalier, Julien de Wit, Mathilde Timmermans +14

Short-period white-dwarf (WD) binaries are post-common-envelope systems that constrain orbital shrinkage, envelope evolution, and the survival of low-mass companions. We report the…

TOI-4552 b: A new ultra-short period rocky world revealed by NIRPS and TESS

Avidaan Srivastava, René Doyon, François Bouchy +57

A particularly intriguing subclass of rocky exoplanets are the ultra-short period (USP) worlds that orbit their host stars in less than a day. These planets are particularly rare a…

TOI-4616 b: a benchmark Earth-sized planet transiting a nearby M4 dwarf

F. Zong Lang, B. O. Demory, Y. Gomez Maqueo Chew +44

Rocky exoplanets are particularly abundant around M-type stars. Their small radii and low luminosities provide favourable conditions for detecting transiting terrestrial planets an…
