Variable pulse profiles of Her X-1 repeating with the same irregular 35d clock as the turn-ons

R. Staubert, D. Klochkov, D. Vasco +4

The accreting X-ray pulsar Her X-1 shows two types of long-term variations, both with periods of ~35 days: 1) Turn-on cycles, a modulation of the flux}, with a ten-day long Main-On…

Spectral curves for Cauchy-Riemann operators on punctured elliptic curves

Christoph Bohle, Iskander A. Taimanov

We show that one can define a spectral curve for the Cauchy-Riemann operator on a punctured elliptic curve if one imposes appropriate boundary conditions. Algebraic curves of the t…

Stellar irradiated discs and implications on migration of embedded planets I: equilibrium discs

Bertram Bitsch, Aurélien Crida, Alessandro Morbidelli +2

The strength and direction of migration of low mass planets depends on the disc's thermodynamics. In discs where the viscous heating is balanced by radiative transport, the migrati…

Nucleon resonances in AdS/QCD

Thomas Gutsche, Valery E. Lyubovitskij, Ivan Schmidt +1

We describe the electroproduction of the N(1440) Roper resonance in soft-wall AdS/QCD. The Roper resonance is identified as the first radially excited state of the nucleon, where h…
