Collisional study of Hilda and quasi-Hilda asteroids

P. S. Zain, R. P. Di Sisto, R. Gil-Hutton

The Hilda asteroids are located in the outer main belt in a stable 3:2 mean-motion resonance with Jupiter, while the quasi-Hildas (qH) have similar orbits but are not directly unde…

Crater production on Titan and surface chronology

N. L. Rossignoli, R. P. Di Sisto, M. G. Parisi

Impact crater counts on the Saturnian satellites are a key element for estimating their surface ages and placing constraints on their impactor population. The Cassini mission radar…

Impacts on Ceres and Vesta: Source regions, cratering, and fragmentation

Patricio Zain, Romina Di Sisto, Gonzalo de Elia

We perform a study on the impacts on Ceres and Vesta. We aim to determine the size-frequency distribution (SFD) of impactors and to identify and quantify the contribution of each s…

Massive search of spot- and facula-crossing events in 1598 exoplanetary transit lightcurves

R. V. Baluev, E. N. Sokov, I. A. Sokova +40

We developed a dedicated statistical test for a massive detection of spot- and facula-crossing anomalies in multiple exoplanetary transit lightcurves, based on the frequentist -…

Planet-star interactions with precise transit timing. II. The radial-velocity tides and a tighter constraint on the orbital decay rate in the WASP-18 system

G. Maciejewski, H. A. Knutson, A. W. Howard +4

From its discovery, the WASP-18 system with its massive transiting planet on a tight orbit was identified as a unique laboratory for studies on tidal planet-star interactions. In a…

Homogeneously derived transit timings for 17 exoplanets and reassessed TTV trends for WASP-12 and WASP-4

R. V. Baluev, E. N. Sokov, H. R. A. Jones +34

We homogeneously analyse photometric measurements for transit lightcurves belonging to exoplanet hosts. The photometric data cover years…

From Centaurs to comets - 40 years

Nuno Peixinho, Audrey Thirouin, Stephen C. Tegler +4

In 1977, while Apple II and Atari computers were being sold, a tiny dot was observed in an inconvenient orbit. The minor body 1977 UB, to be named (2060) Chiron, with an orbit betw…

Cratering and age of the small Saturnian satellites

N. L. Rossignoli, R. P. Di Sisto, M. Zanardi +1

The small ( 135 km mean radius) saturnian satellites are closely related to the rings and together they constitute a complex dynamical system where formation and destruction m…

The role of the general relativity on icy body reservoirs under the effects of an inner eccentric Jupiter

Macarena Zanardi, Gonzalo Carlos de Elía, Romina P. Di Sisto +1

Recent studies have analyzed the dynamical evolution of outer small body populations under the effects of an eccentric inner massive perturber. Such outer reservoirs are composed o…

Giga-Year Evolution of Jupiter Trojans and the Asymmetry Problem

Romina P. Di Sisto, Ximena S. Ramos, Cristián Beaugé

We present a series of numerical integrations of observed and fictitious Jupiter Trojan asteroids, under the gravitational effects of the four outer planets, for time-spans compara…

Origin of craters on Phoebe: comparison with Cassini's data

R. P. Di Sisto, A. Brunini

Phoebe is one of the irregular satellites of Saturn; the images taken by Cassini-Huygens spacecraft allowed us to analyze its surface and the craters on it. We study the craters on…
