An Extremely Top-Heavy IMF in the Galactic Center Stellar Disks
H. Bartko, F. Martins, S. Trippe +19
We present new observations of the nuclear star cluster in the central parsec of the Galaxy with the adaptive optics assisted, integral field spectrograph SINFONI on the ESO/VLT. O…
A faint type of supernova from a white dwarf with a helium-rich companion
H. B. Perets, A. Gal-Yam, P. Mazzali +25
Supernovae (SNe) are thought to arise from two different physical processes. The cores of massive, short-lived stars undergo gravitational core collapse and typically eject a few s…
Dynamical evolution of the young stars in the Galactic center: N-body simulations of the S-stars
Hagai B. Perets, Alessia Gualandris, Gabor Kupi +2
We use N-body simulations to study the evolution of the orbital eccentricities of stars deposited near (<0.05 pc) the Milky Way massive black hole (MBH), starting from initial cond…
The Galactic Center: A Laboratory for Fundamental Astrophysics and Galactic Nuclei
A. Ghez, M. Morris, J. Lu +24
As the closest example of a galactic nucleus, the Galactic center presents an exquisite laboratory for learning about supermassive black holes (SMBH) and their environs. Detailed s…
Classical Diffusion of a quantum particle in a noisy environment
Ariel Amir, Yoav Lahini, Hagai B. Perets
We study the spreading of a quantum-mechanical wavepacket in a one-dimensional tight-binding model with a noisy potential, and analyze the emergence of classical diffusion from the…
On the triple origin of blue stragglers
Hagai B. Perets, Daniel C. Fabrycky
Blue straggler stars (BSSs) are stars observed to be hotter and bluer than other stars with the same luminosity in their environment. As such they appear to be much younger than th…
