Wind-shearing in gaseous protoplanetary disks
Hagai B. Perets, Ruth Murray-Clay
One of the first stages of planet formation is the growth of small planetesimals and their accumulation into large planetesimals and planetary embryos. This early stage occurs much…
Binary planetesimals and their role in planet formation
Hagai B. Perets
One of the main evolutionary stages of planet formation is the dynamical evolution of planetesimal disks. These disks are thought to evolve through gravitational encounters and phy…
Interaction of Atomic and Molecular Hydrogen with Tholin Surfaces at Low Temperatures
Ling Li, Hui Zhao, Gianfranco Vidali +4
We study the interaction of atomic and molecular hydrogen with a surface of tholin, a man-made polymer considered to be an analogue of aerosol particles present in Titan's atmosphe…
Helium Shell Detonations on Low Mass White Dwarfs as a Possible Explanation for SN 2005E
Roni Waldman, Daniel Sauer, Eli Livne +5
Recently several type Ib supernovae (SNe; with the prototypical SN 2005E) have been shown to have atypical properties. These SNe are faint (absolute peak magnitude of ~ -15) and fa…
An Emerging Class of Bright, Fast-evolving Supernovae with Low-mass Ejecta
Hagai B. Perets, Carles Badenes, Iair Arcavi +2
A recent analysis of supernova (SN) 2002bj revealed that it was an apparently unique type Ib SN. It showed a high peak luminosity, with absolute magnitude M_R -18.5, but an extreme…
Dynamical constraints on the origin of the young B-stars in the Galactic center
Hagai B. Perets, Alessia Gualandris
Regular star formation is thought to be inhibited close to the massive black hole (MBH) in the Galactic center. Nevertheless, tens of young main sequence B stars have been observed…
Dynamics and origins of the young stars in the Galactic center
Hagai B. Perets
The environment near the massive black hole (MBH) in the Galactic center is very hostile for star formation. Nevertheless, many young stars (both O and B stars) are observed close…
Second generation planets
Hagai B. Perets
Planets are typically thought to form in protoplanetary disks left over from protostellar disk of their newly formed host star. However, an additional planetary formation route may…
Massive Young Stars in the Galactic Center
H. Bartko
We summarize our latest observations of the nuclear star cluster in the central parsec of the Galaxy with the adaptive optics assisted, integral field spectrograph SINFONI on the E…
Orbital properties of binary minor planets
Smadar Naoz, Hagai B. Perets, Darin Ragozzine
Many binary minor planets (BMPs; both binary asteroids and binary Trans-Neptunians objects; TNOs) are known to exist in the Solar system. The currently observed orbital and physica…
