Contemporary formation of early solar system planetesimals at two distinct radial locations
Alessandro Morbidelli, Kevin Baillie, Konstantin Batygin +4
The formation of planetesimals is expected to occur via particle-gas instabilities that concentrate dust into self-gravitating clumps. Triggering these instabilities requires the p…
A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE).XI. Two dimensional H kinematics of the edge-on ram pressure stripped galaxy NGC 4330
M. M. Sardaneta, P. Amram, A. Boselli +18
Using the VESTIGE survey, a deep narrow-band H imaging survey of the Virgo cluster carried on at the CFHT with MegaCam, we discovered a long diffuse tail of ionised gas in the e…
Resurfacing processes constrained by crater distribution on Ryugu
Naofumi Takaki, Yuichiro Cho, Tomokatsu Morota +16
Understanding the geological modification processes on asteroids can provide information concerning their surface history. Images of small asteroids from spacecraft show a depletio…
EUSO@TurLab project in view of Mini-EUSO and EUSO-SPB2 missions
H. Miyamoto, M. E. Bertaina, D. Barghini +37
The TurLab facility is a laboratory, equipped with a 5 m diameter and 1 m depth rotating tank, located in the fourth basement level of the Physics Department of the University of T…
Spectrum of kinetic plasma turbulence at 0.3-0.9 astronomical units from the Sun
Olga Alexandrova, Vamsee Krishna Jagarlamudi, Petr Hellinger +3
We investigate spectral properties of turbulence in the solar wind that is a weakly collisional astrophysical plasma, accessible to in-situ observations. Using the Helios search co…
An absolute calibration of the near-infrared Period-Luminosity Relations of Type II Cepheids in the Milky Way and in the Large Magellanic Cloud
Piotr Wielgórski, Grzegorz Pietrzyński, Bogumił Pilecki +29
We present time-series photometry of 21 nearby Type II Cepheids in the near-infrared J, H and Ks passbands. We use this photometry, together with the Third Gaia Early Data Release…
