A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067
R. Luque, H. P. Osborn, A. Leleu +149
Planets with radii between that of the Earth and Neptune (hereafter referred to as sub-Neptunes) are found in close-in orbits around more than half of all Sun-like stars. Yet, thei…
The "Drake equation" of exomoons -- a cascade of formation, stability and detection
Gy. M. Szabó, J. Schneider, Z. Dencs +1
After 25 years of the prediction of the possibility of observations, and despite the many hundreds of well studied transiting exoplanet systems, we are still waiting for the announ…
No random transits in CHEOPS observations of HD 139139
R. Alonso, S. Hoyer, M. Deleuil +78
HD 139139 (a.k.a. 'The Random Transiter') is a star that exhibited enigmatic transit-like features with no apparent periodicity in K2 data. The shallow depth of the events (2…
Refining the properties of the TOI-178 system with CHEOPS and TESS
L. Delrez, A. Leleu, A. Brandeker +84
The TOI-178 system consists of a nearby late K-dwarf transited by six planets in the super-Earth to mini-Neptune regime, with orbital periods between 1.9 and 20.7 days. All planets…
Mitigating potentially hazardous asteroid impacts revisited
Zs. Regaly, V. Frohlich, P. Berczik
Context: Potentially hazardous asteroids (PHA) in Earth-crossing orbits pose a constant threat to life on Earth. Several mitigation methods have been proposed, and the most feasibl…
Investigating the porosity of Enceladus
Imre Kisvárdai, Bernadett D. Pál, Ákos Kereszturi
The interior of Enceladus, a medium sized icy moon of Saturn hosts hydrothermal activity and exhibits tidal heating and related geyser-like activity. There are major disagreements…
Investigating the visible phase-curve variability of 55 Cnc e
E. A. Meier Valdés, B. M. Morris, B. -O. Demory +87
55 Cnc e is an ultra-short period super-Earth transiting a Sun-like star. Previous observations in the optical range detected a time-variable flux modulation that is phased with th…
Spirals and clumps in V960 Mon: signs of planet formation via gravitational instability around an FU Ori star?
P. Weber, S. Pérez, A. Zurlo +11
The formation of giant planets has traditionally been divided into two pathways: core accretion and gravitational instability. However, in recent years, gravitational instability h…
TESS and CHEOPS Discover Two Warm Sub-Neptunes Transiting the Bright K-dwarf HD 15906
Amy Tuson, Didier Queloz, Hugh P. Osborn +119
We report the discovery of two warm sub-Neptunes transiting the bright (G = 9.5 mag) K-dwarf HD 15906 (TOI 461, TIC 4646810). This star was observed by the Transiting Exoplanet Sur…
Refined parameters of the HD 22946 planetary system and the true orbital period of planet d
Z. Garai, H. P. Osborn, D. Gandolfi +85
Multi-planet systems are important sources of information regarding the evolution of planets. However, the long-period planets in these systems often escape detection. HD 22946 is…
Two Warm Neptunes transiting HIP 9618 revealed by TESS & Cheops
Hugh P. Osborn, Grzegorz Nowak, Guillaume Hébrard +126
HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright ( mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of …
TOI-5678 b: A 48-day transiting Neptune-mass planet characterized with CHEOPS and HARPS
S. Ulmer-Moll, H. P. Osborn, A. Tuson +92
A large sample of long-period giant planets has been discovered thanks to long-term radial velocity surveys, but only a few dozen of these planets have a precise radius measurement…
A dynamical survey of the trans-Neptunian region II.: On the nature of chaotic diffusion
Emese Kővári, Emese Forgács-Dajka, Tamás Kovács +2
On long enough timescales, chaotic diffusion has the potential to significantly alter the appearance of a dynamical system. The solar system is no exception: diffusive processes ta…
Discovery of a substellar companion in the TESS light curve of the Scuti/ Doradus hybrid pulsator HD 31221
Sz. Kálmán, A. Derekas, Sz. Csizmadia +9
Close-in, sub-stellar companions to Scuti type stars present a highly suitable testbed for examining how planetary-mass objects can influence stellar pulsations. We aim to cons…
Converting the sub-Jovian desert of exoplanets to a savanna with TESS, PLATO and Ariel
Szilárd Kálmán, Gyula M. Szabó, Luca Borsato +3
There is a lack of exoplanets with sizes similar to Neptune orbiting their host stars with periods days -- hence the name ``sub-Jovian/Neptune desert''. Recently, seve…
A new dynamical modeling of the WASP-47 system with CHEOPS observations
V. Nascimbeni, L. Borsato, T. Zingales +80
Among the hundreds of known hot Jupiters (HJs), only five have been found to have companions on short-period orbits. Within this rare class of multiple planetary systems, the archi…
TOI-1055 b: Neptunian planet characterised with HARPS, TESS, and CHEOPS
A. Bonfanti, D. Gandolfi, J. A. Egger +89
TOI-1055 is a Sun-like star known to host a transiting Neptune-sized planet on a 17.5-day orbit (TOI-1055 b). Radial velocity (RV) analyses carried out by two independent groups us…
Glancing through the debris disk: Photometric analysis of DE Boo with CHEOPS
Á. Boldog, Gy. M. Szabó, L. Kriskovics +76
DE Boo is a unique system, with an edge-on view through the debris disk around the star. The disk, which is analogous to the Kuiper belt in the Solar System, was reported to extend…
