Circularization of tidal debris around white dwarfs: implications for gas production and dust variability
Uri Malamud, Evgeni Grishin, Marc Brouwers
White dwarf (WD) pollution is thought to arise from the tidal disruption of planetary bodies. The initial fragment stream is extremely eccentric, while observational evidence sugge…
The Wide-Binary Origin of The Pluto-Charon System
Mor Rozner, Evgeni Grishin, Hagai B. Perets
The Pluto-Charon binary system is the best-studied representative of the binary Kuiper-belt population. Its origins are vital to understanding the formation of other Kupier-belt ob…
Erosion driven size-redistribution of protoplanetary disk solids and the onset of streaming Instability and Pebble Accretion
Evgeni Grishin, Mor Rozner, Hagai B. Perets
The formation of the first planetesimals and the final growth of planetary cores relies on the abundance of small pebbles. The efficiencies of both the streaming instability (SI) p…
Origin of (2014) MU69-like Kuiper-belt contact binaries from wide binaries
Evgeni Grishin, Uri Malamud, Hagai B. Perets +2
Following its flyby and first imaging the Pluto-Charon binary, the New Horizons spacecraft visited the Kuiper-Belt-Object (KBO) (486958) 2014 MU69 (Arrokoth). Imaging showed MU69 t…
The CARMENES search for exoplanets around M dwarfs. Dynamical characterization of the multiple planet system GJ 1148 and prospects of habitable exomoons around GJ 1148 b
T. Trifonov, M. H. Lee, M. Kürster +29
Context. GJ 1148 is an M-dwarf star hosting a planetary system composed of two Saturn-mass planets in eccentric orbits with periods of 41.38 and 532.02 days. Aims. We reanalyze the…
The aeolian-erosion barrier for the growth of metre-size objects in protoplanetary-discs
Mor Rozner, Evgeni Grishin, Hagai B. Perets
Aeolian-erosion is a destructive process which can erode small-size planetary objects through their interaction with a gaseous environment. Aeolian-erosion operates in a wide range…
