We use a high signal-to-noise MIRI-LRS spectrum (5.45 - 11 m, R ) of COCONUTS-2~b revealing prominent molecular features of HO, CH and NH. This dataset…
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…
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…
Detecting false positives with PLATO using double-aperture photometry and centroid shifts
F. Gutiérrez-Canales, R. Samadi, A. Birch +6
PLATO will discover exoplanets around Sun-like stars through transit photometry and characterize their host stars using asteroseismology. Since photometry for most PLATO targets wi…
The MATISSE view of the inner region of the RY Tau protoplanetary disk
J. S. Martin, J. Kobus, J. Varga +44
The T-Tauri type young stellar object RY Tau exhibits a dust depleted inner cavity characteristic of a transition disk. We constrain the spatial distribution and mineralogy of dust…
MINDS. Strong oxygen depletion in the inner regions of a very low-mass star disk?
Jayatee Kanwar, Inga Kamp, Peter Woitke +10
JWST is discovering a plethora of species in planet-forming disks around very low-mass stars such as C2H2, C6H6, C4H2, CH3 etc. The column densities of these species retrieved from…
The vertical structure of debris discs and the role of disc gravity: A primer using a simplified model
Antranik A. Sefilian, Kaitlin M. Kratter, Mark C. Wyatt +4
Debris discs provide valuable insights into the formation and evolution of exoplanetary systems. Their structures are commonly attributed to planetary perturbations, serving as pro…
Stellar Models Also Limit Exoplanet Atmosphere Studies in Emission
Thomas J. Fauchez, Elsa Ducrot, Benjamin V. Rackham +3
Stellar contamination has long been recognized as a major bottleneck in transmission spectroscopy, limiting our ability to accurately characterize exoplanet atmospheres-particularl…
The PLATO field selection process. II. Characterization of LOPS2, the first long-pointing field
V. Nascimbeni, G. Piotto, J. Cabrera +26
PLAnetary Transits and Oscillations of stars (PLATO) is an ESA M-class mission to be launched by the end of 2026 to discover and characterize transiting planets around bright and n…
Stellar occultations by Trans-Neptunian Objects
Bruno Sicardy, Felipe Braga-Ribas, Marc W. Buie +2
Stellar occultations provide a powerful tool to explore objects of the outer solar system. The Gaia mission now provides milli-arcsec accuracy on the predictions of these events an…
Abundances of trace constituents in Jupiter's atmosphere inferred from Herschel/PACS observations
Cyril Gapp, Miriam Rengel, Paul Hartogh +4
On October 31, 2009, the Photodetector Array Camera and Spectrometer (PACS) on board the Herschel Space Observatory observed far-infrared spectra of Jupiter between 50 a…
Artificial Greenhouse Gases as Exoplanet Technosignatures
Edward W. Schwieterman, Thomas J. Fauchez, Jacob Haqq-Misra +6
Atmospheric pollutants such as CFCs and NO have been proposed as potential remotely detectable atmospheric technosignature gases. Here we investigate the potential for artifi…
A chaotic long-lived vortex at Venus southern pole
I. Garate-Lopez, R. Hueso, A. Sánchez-Lavega +3
Polar vortices are common in the atmospheres of rapidly rotating planets [1-4]. On Earth and Mars they are tied to the surface and their existence follows the seasonal insolation c…
On Earth's habitability over the Sun's main-sequence history: joint influence of space weather and Earth's magnetic field evolution
