Accessible does not mean exploitable: HiPERCAM reveals the ultra-fast rotation of 2022 OB
Miguel R. Alarcon, Javier Licandro, Miquel Serra-Ricart +2
2022 OB is a sub-10-metre Apollo-type near-Earth asteroid whose orbital configuration placed it among the most dynamically accessible small bodies in near-Earth space, motivati…
A High-Throughput AES-GCM Implementation on GPUs for Secure, Policy-Based Access to Massive Astronomical Catalogs
Samuel Lemes-Perera, Miguel R. Alarcon, Pino Caballero-Gil +1
The era of large astronomical surveys generates massive image catalogs requiring efficient and secure access, particularly during pre-publication periods where data confidentiality…
TOI-7166 b: A Habitable Zone mini-Neptune planet around a nearby low-mass star
Khalid Barkaoui, Francisco J. Pozuelos, Benjamin V. Rackham +41
We present the discovery and validation of TOI-7166b, a 2.01+/-0.05R_Earth planet orbiting a nearby low-mass star. We validated the planet by combining TESS and multi-color high-pr…
NIRPS and TESS reveal a peculiar system around the M dwarf TOI-756: A transiting sub-Neptune and a cold eccentric giant
Léna Parc, François Bouchy, Neil J. Cook +148
The Near InfraRed Planet Searcher (NIRPS) joined HARPS on the 3.6-m ESO telescope at La Silla Observatory in April 2023, dedicating part of its Guaranteed Time Observations (GTO) p…
Quantifying thermal water dissociation in the dayside photosphere of WASP-121 b using NIRPS
Luc Bazinet, Romain Allart, Björn Benneke +119
The intense stellar irradiation of ultra-hot Jupiters results in some of the most extreme atmospheric environments in the planetary regime. On their daysides, temperatures can be s…
Diving into the planetary system of Proxima with NIRPS -- Breaking the metre per second barrier in the infrared
Alejandro Suárez Mascareño, Étienne Artigau, Lucile Mignon +138
We obtained 420 high-resolution spectra of Proxima, over 159 nights, using the Near Infra Red Planet Searcher (NIRPS). We derived 149 nightly binned radial velocity measurements wi…
NIRPS detection of delayed atmospheric escape from the warm and misaligned Saturn-mass exoplanet WASP-69b
Romain Allart, Yann Carteret, Vincent Bourrier +119
Near-infrared high-resolution echelle spectrographs unlock access to fundamental properties of exoplanets, from their atmospheric escape and composition to their orbital architectu…
Blind search for activity-sensitive lines in the near-infrared using HARPS and NIRPS observations of Proxima and Gl 581
João Gomes da Silva, Elisa Delgado-Mena, Nuno C. Santos +145
Stellar activity variability is one of the main obstacles to the detection of Earth-like planets using the RV method. The aim of this work is to measure the effect of activity in t…
Hydride ion continuum hides absorption signatures in the NIRPS near-infrared transmission spectrum of the ultra-hot gas giant WASP-189b
Valentina Vaulato, Stefan Pelletier, David Ehrenreich +77
Ultra-hot Jupiters showcase extreme atmospheric conditions, including molecular dissociation, ionisation, and significant day-to-night temperature contrasts. Their close proximity…
Revisiting the multi-planetary system of the nearby star HD 20794: Confirmation of a low-mass planet in the habitable zone of a nearby G-dwarf
N. Nari, X. Dumusque, N. C. Hara +44
Close-by Earth analogs and super-Earths are of primary importance because they will be preferential targets for the next generation of direct imaging instruments. Bright and close-…
Cosmological impact of microwave background temperature measurements
L. Gelo, C. J. A. P. Martins, N. Quevedo +1
The cosmic microwave background temperature is a cornerstone astrophysical observable. Its present value is tightly constrained, but its redshift dependence, which can now be deter…
Lithium ions solvated in helium
Monisha Rastogi, Christian Leidlmair, Lukas An der Lan +10
We report on a combined experimental and theoretical study of Li ions solvated by up to 50 He atoms. The experiments show clear enhanced abundances associated with HeLi…
Kepler White Paper: Asteroseismology of Solar-Like Oscillators in a 2-Wheel Mission
W. J Chaplin, H. Kjeldsen, J. Christensen-Dalsgaard +53
We comment on the potential for continuing asteroseismology of solar-type and red-giant stars in a 2-wheel Kepler Mission. Our main conclusion is that by targeting stars in the ecl…
