The Maunder Model and Catalog: Stellar Rotation, Bimodal Activity, and Magnetic Braking in Kepler Main-Sequence Stars
Ilay Kamai, Lavi Somers, Hagai B. Perets
We present The Maunder, a machine learning pipeline and resulting catalog of rotation periods for 148,746 main-sequence stars in the Kepler field. To overcome single-catalog system…
Superdiffusion at the Galactic Centre
Pau Amaro Seoane, Kostas Tzanavaris, Reinhard Genzel +14
The paper models the orbital evolution of the S‑star cluster around the Milky Way’s central black hole using a superdiffusive, fractional transport framework that accounts for long…
Stellar rotation of S301 as a macroscopic gyroscope to test general relativity
Pau Amaro Seoane, Xian Chen, Alejandro Torres-Orjuela +16
The paper studies how the rotation of the S301 star near the Galactic Center can act as a macroscopic gyroscope, using its relativistic precession to test general relativity with i…
Helium Accumulation and Thermonuclear Instabilities on Accreting White Dwarfs: From Recurring Helium Novae to Type Ia Supernovae
Yael Hillman, Amir Michaelis, Hagai B. Perets
We investigate helium accumulation on carbon-oxygen (CO) white dwarfs (WDs), exploring a broad parameter space of initial WD masses (--) and helium accretion ra…
Sub-Snowline Formation of Gas-Giant Planets in Binary Systems
Ilay Kamai, Hagai B. Perets, Jakob Stegmann +1
Gas-giant planets are thought to require conditions beyond the water snow line to build solid cores efficiently. In close binary star systems, the companion's gravity additionally…
Ultra-long Gamma-ray Bursts from Micro-Tidal Disruption Events: The Case of GRB 250702B
Paz Beniamini, Hagai B. Perets, Jonathan Granot
Ultra-long gamma-ray bursts (ULGRBs), a rare class of high-energy transients with durations s, remain poorly understood. GRB 250702B is notable for its multi-hour prompt emi…
