Continuous Wide-Field Optical Monitoring for Very Early-Phase Transient Discovery
Massimo Della Valle, Maria Teresa Botticella, Enrico Cappellaro +40
The study of transient phenomena in a multimessenger context is expected to remain a major pillar of astrophysical discovery in the decades ahead. Supernovae, Kilonovae, Black-Hole…
Selection and characterisation of the M-dwarf targets in the PLATO Input Catalogue
L. Prisinzano, M. Montalto, G. Piotto +33
The ESA's PLAnetary Transits and Oscillations of Stars (PLATO) mission aims to detect planets orbiting around dwarfs and subgiant stars with spectral type F5 or later, including M-…
Giant Outer Transiting Exoplanet Mass (GOTEM) Survey.VII. TOI-6041: a multi-planet system including a warm Neptune exhibiting strong TTVs
N. Heidari, A. Alnajjarine, H. P. Osborn +101
We present the characterization of the TOI-6041 system, a bright () G7-type star hosting at least two planets. The inner planet, TOI-6041b, is a warm Neptune wit…
HARPS-N, TESS, and CHEOPS discover a transiting sub-Neptune and two outer companions around the bright solar analogue HD 85426
F. Lienhard, A. Mortier, A. Collier Cameron +96
We provide a detailed characterisation of the planetary system orbiting HD 85426 (TOI-1774). This bright G-type star (: 0.99 ; : 1.13 $\text{R…
Transit Timing Variations in HIP 41378: CHEOPS and TESS confirm a non-transiting sixth planet in the system
P. Leonardi, L. Borsato, L. Pagliaro +89
In multiple-planet systems, gravitational interactions of exoplanets could lead to transit timing variations (TTVs), whose amplitude becomes significantly enhanced when planets are…
An Ultra-Short Period Super-Earth and Sub-Neptune Spanning the Radius Valley Orbiting the Kinematic Thick Disk Star TOI-2345
Yoshi Nike Emilia Eschen, Thomas G. Wilson, Andrea Bonfanti +94
A crucial chemical link between stars and their orbiting exoplanets is thought to exist. If universal, this connection could affect the formation and evolution of all planets. Ther…
A high geometric albedo and small size of the Haumea cluster member (24835) 1995 SM55 from a stellar occultation and photometric observations
J. L. Ortiz, N. Morales, B. Sicardy +98
Trans-Neptunian objects (TNOs) are among the most ancient bodies of the solar system. Understanding their physical properties is key to constraining their origin and the evolution…
A four-planet system orbiting the old thick disk star TOI-1203
D. Gandolfi, A. Alnajjarine, L. M. Serrano +120
TOI-1203 is a bright (V=8.6) G3 V star known to host a transiting warm sub-Neptune on a 25.5 d orbit. Here we report on an intensive high-precision radial velocity and photometric…
Improved characterization of the TOI-2141 system: a dense sub-Neptune with non-transiting inner and outer companions
R. Luque, K. W. F. Lam, J. Cabrera +87
We aim to refine the fundamental parameters of the TOI-2141 planetary system, which includes a transiting sub-Neptune orbiting a Sun-like star in a relatively long orbit of 18.26 d…
The Corona-Australis star-forming region: New insights on its formation history from detailed stellar and disk analysis
Elisabetta Rigliaco, Raffaele Gratton, Valerio Nascimbeni
The star-forming complex of Corona Australis (CrA) is one of the closest and most isolated molecular clouds. It belongs to a chain of clusters that show age gradients with distance…
The GAPS Programme at TNG. LXIX.The Dayside of WASP-76b revealed by GIANO-B, HARPS-N and ESPRESSO: Evidence for Three-Dimensional Atmospheric Effects
G. Guilluy, P. Giacobbe, M. Brogi +22
The study of the atmosphere of ultra-hot Jupiters (UHJs) with equilibrium temperature 2000 K provides valuable insights into atmospheric physics under such extreme conditions…
The CHEOPS view of HD 95338b: refined transit parameters, and a search for exomoons
Sz. Kálmán, A. E. Simon, A. Deline +90
Despite the ever-increasing number of known exoplanets, no uncontested detections have been made of their satellites, known as exomoons. The quest to find exomoons is at the forefr…
The KELT-7b atmospheric thermal-inversion conundrum revisited with CHEOPS, TESS, and additional data
Z. Garai, A. Krenn, P. E. Cubillos +84
Ultrahot Jupiters are predicted to show inverted temperature-pressure (T-P) profiles in the presence of optical absorbers such as TiO and VO. An inverted T-P profile of KELT-7b was…
Dark skies of the slightly eccentric WASP-18 b from its optical-to-infrared dayside emission
A. Deline, P. E. Cubillos, L. Carone +86
We performed a joint analysis of phase-curve observations of the ultra-hot Jupiter WASP-18 b from the visible to the mid-infrared, using data from CHEOPS, TESS and Spitzer. We aim…
