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…
The EBLM Project - XIX. The absence of radius inflation in a homogeneous analysis of 66 Northern low-mass eclipsing binaries
Yasmin T. Davis, Amaury H. M. J. Triaud, David V. Martin +30
Precise and accurate measurements of host stars are crucial in the search for Earth-like exoplanets, and M-dwarfs are favourable targets in this quest. Low-mass eclipsing binaries…
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*=…
NGTS clusters survey - VII. An Enigmatic Short-Period Circumsecondary Disk Candidate in Orion
Niamh Mallaghan, Ernst J. W. de Mooij, Christopher A. Watson +31
Young stellar systems provide key insights into the processes governing star/planet formation, often exhibiting complex and evolving photometric variability. In this paper, we pres…
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…
ASTEP confirmation of a pair of long-period Jupiter-sized planets with extremely low densities transiting TOI-791
Georgina Dransfield, Antoine C. Petit, Amaury H. M. J. Triaud +45
Gas giant planets with periods orbiting Sun-like stars are a relatively uncommon outcome of planetary formation, and key questions about the nature and form…
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…
J0404+1112: A 3-Hour Eclipsing White Dwarf-Brown Dwarf Probing Multiple Atmospheric Regimes
J. de Wit, R. Alonso, B. V. Rackham +19
White dwarf-brown dwarf (WD+BD) binaries are rare laboratories for probing both substellar survival through post-main-sequence evolution and the physics of strongly irradiated atmo…
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…
A Panchromatic JWST Spectrum of a Giant Starspot on the Fully Convective M-dwarf TOI-3884
C. A. Murray, L. Garcia, B. V. Rackham +18
TOI-3884 b is a rare super-Neptune transiting a fully convective M dwarf that hosts a persistent giant polar spot. Because the planet occults this active region during every transi…
TOI-1080 b: a temperate, rocky planet orbiting a quiet M4V host
Y. Gómez Maqueo Chew, G. Dransfield, K. Barkaoui +41
We present the detection and validation of a small, temperate transiting exoplanet orbiting TOI-1080 every 3.9652482 days. The host is a quiet M4V star…
Hidden Gems in TESS: sherlock finds two new rocky planets around nearby M dwarfs
M. Timmermans, M. Dévora-Pajares, F. J. Pozuelos +25
The Hidden Gems project searches the TESS data for additional planets transiting low-mass stars in confirmed systems. Our goal is to identify planet candidates that are below the d…
Two temperate Earth- and Neptune-sized planets orbiting fully convective M dwarfs
Madison G. Scott, Georgina Dransfield, Mathilde Timmermans +30
As the diversity of exoplanets continues to grow, it is important to revisit assumptions about habitability and classical HZ definitions. In this work, we introduce an expanded 'te…
