The GAPS programme at TNG: LXXVI. TOI-1533: a compact system hosting a super-Neptune-mass pair with disparate radii
G. Mantovan, V. Nascimbeni, S. Desidera +49
The present-day architecture of planetary systems contains information about their formation and migration histories. The origin of hot Jupiters (HJs, P 10 d, $R_{\rm p}…
Planet formation in chemically diverse and evolving discs II. Chemical fingerprints in planetary atmospheres
E. Pacetti, D. Turrini, E. Schisano +13
Giant planets form in protoplanetary discs, where the coupled dynamical and chemical evolution of gas and solids determines the composition of the material they accrete. We investi…
Demographics of planet-forming disks with the SKAO
Antonio Garufi, Sebastián Pérez, John D. Ilee +21
Understanding how solid material in planet-forming disks evolves from micron-sized dust to planetary cores is a central challenge in modern astrophysics. This study has advanced dr…
Mercury-Opal: the GPU-accelerated version of the n-body code for planet formation Mercury-Arxes
Paolo Simonetti, Diego Turrini, Romolo Politi +4
Large n-body simulations with fully interacting objects represent the next frontier in computational planetary formation studies. In this paper, we present Mercury-Opal, the GPU-ac…
The Origins of Planets for ArieL (OPAL) Key Science Project: the end-to-end planet formation campaign for the ESA space mission Ariel
Danae Polychroni, Diego Turrini, Romolo Politi +7
The growing body of atmospheric observations of exoplanets from space and ground-based facilities showcases how the great diversity of the planetary population is not limited to th…
Mercury-Ares: a high-performance n-body code for planet formation studies
Diego Turrini, Sergio Fonte, Romolo Politi +4
Forming planetary systems are populated by large numbers of gravitationally interacting planetary bodies, spanning from massive giant planets to small planetesimals akin to present…
The quest for Magrathea planets. II. Orbital stability of exoplanets formed around double white dwarfs
Arianna Nigioni, Diego Turrini, Camilla Danielski +2
Planetary formation might occur at different stages of the stellar evolution of compact binaries. In recent years, the formation of second-generation planets has been tested in cir…
The GAPS programme at TNG LXXI. A sub-Neptune suitable for atmospheric characterization in a multiplanet and mutually inclined system orbiting the bright K dwarf TOI-5789 (HIP 99452)
A. S. Bonomo, L. Naponiello, A. Sozzetti +37
Sub-Neptunes with planetary radii of are the most common planets around solar-type stars in short-period ( d) orbits. It is still unclear, howe…
The Hot Neptune Initiative (HONEI) II. TOI-5795 b: A hot super-Neptune orbiting a metal-poor star
F. Manni, L. Naponiello, L. Mancini +31
The formation of Neptune planets with orbital periods less than 10\,days remains uncertain. They might have developed similarly to longer-period counterparts, emerged from rare col…
Planet formation in chemically diverse and evolving discs -- I. Composition of planetary building blocks
E. Pacetti, E. Schisano, D. Turrini +12
Protoplanetary discs are dynamic environments where the interplay between chemical processes and mass transport shapes the composition of gas and dust available for planet formatio…
HD 163296 and its Giant Planets: Creation of Exo-comets, Interstellar Objects and Transport of Volatile Material
D. Polychroni, D. Turrini, S. Ivanovski +14
The birth of giant planets in protoplanetary disks is known to alter the structure and evolution of the disk environment, but most of our knowledge focuses on its effects on the ob…
A joint effort to discover and characterize two resonant mini Neptunes around TOI-1803 with TESS, HARPS-N and CHEOPS
T. Zingales, L. Malavolta, L. Borsato +130
We present the discovery of two mini Neptunes near a 2:1 orbital resonance configuration orbiting the K0 star TOI-1803. We describe their orbital architecture in detail and suggest…
The GAPS programme at TNG LXIV: An inner eccentric sub-Neptune and an outer sub-Neptune-mass candidate around BD+00 444 (TOI-2443)
L. Naponiello, A. S. Bonomo, L. Mancini +25
We examined in depth the star BD+00 444 (GJ 105.5, TOI-2443; V = 9.5 mag; d = 23.9 pc), with the aim of characterizing and confirming the planetary nature of its small companion, t…
TOI-837 b: characterisation, formation and evolutionary history of an infant warm Saturn-mass planet
M. Damasso, D. Polychroni, D. Locci +15
We aim to determine the fundamental properties of the 35 Myr old star TOI-837 and its close-in Saturn-sized planet, and to investigate the system's formation and evolutionary…
Orbital obliquity of the young planet TOI-5398 b and the evolutionary history of the system
G. Mantovan, L. Malavolta, D. Locci +19
Multi-planet systems exhibit remarkable architectural diversity. However, short-period giant planets are typically isolated. Compact systems like TOI-5398, with an outer close-orbi…
The GAPS program at TNG XLVII: The unusual formation history of V1298 Tau
D. Turrini, F. Marzari, D. Polychroni +33
Observational data from space and ground-based campaigns reveal that the 10-30 Ma old V1298 Tau star hosts a compact and massive system of four planets. Mass estimates for the two…
Oxygen depletion in giant planets with different formation histories
S. Fonte, D. Turrini, E. Pacetti +5
The atmospheric C/O ratio of exoplanets is widely used to constrain their formation. To guarantee that the C/O ratio provides robust information, we need to accurately quantify the…
Dust-to-gas ratio resurgence in circumstellar disks due to the formation of giant planets: the case of HD 163296
D. Turrini, F. Marzari, D. Polychroni +1
The amount of dust present in circumstellar disks is expected to steadily decrease with age due to the growth from micron-sized particles to planetesimals and planets. Mature circu…
