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…
Improved Algorithm for the Network Alignment Problem with Application to Binary Diffing
Elie Mengin, Fabrice Rossi
In this paper, we present a novel algorithm to address the Network Alignment problem. It is inspired from a previous message passing framework of Bayati et al. [2] and includes sev…
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…
The Physical Properties of the SVS 13 Protobinary System: Two Circumstellar Disks and a Spiraling Circumbinary Disk in the Making
Ana K. Diaz-Rodriguez, Guillem Anglada, Guillermo Blázquez-Calero +13
We present VLA and ALMA observations of the close (0.3" = 90 au separation) protobinary system SVS 13. We detect two small circumstellar disks (radii 12 and 9 au in dus…
Spin-orbit coupling for close-in planets
Alexandre C. M. Correia, Jean-Baptiste Delisle
We study the spin evolution of close-in planets in multi-body systems and present a very general formulation of the spin-orbit problem. This includes a simple way to probe the spin…
Hidden in Plain Sight: UVIT and MUSE Discovery of a Large, Diffuse Star-Forming Galaxy
Jyoti Yadav, Mousumi Das, Sudhanshu Barway +1
We report the discovery of a nearby large, diffuse galaxy that shows star formation, using Ultra Violet Imaging Telescope (UVIT) far-UV observations, archival optical data from Mul…
