Long-term evolution of cyclotron resonant scattering features in the accreting pulsar Vela X-1: A pulse-to-pulse approach

Astronomy & Astrophysics
We investigated the long-term evolution of the cyclotron line energy, as well as the relationship between cyclotron line energy and luminosity in the high-mass X-ray binary Vela X-1, based on archival Swift/BAT monitoring from 2005 to 2024 and pulse-to ...

A robust super-time-stepping scheme for Ohmic and ambipolar diffusion

Astronomy & Astrophysics
Context. Nonideal magnetohydrodynamics (MHD) is a key tool for modeling magnetic flux transport in astrophysical systems such as molecular clouds, protostellar cores, and protoplanetary disks.

Mass distribution of population III star clusters: A-SLOTH predictions for JWST observability

Astronomy & Astrophysics
Context. Detecting population III (pop. III) stars remains a major observational challenge. Their Balmer-series recombination line emission, redshifted into the infrared at z ∼ 5 − 11, has been proposed as a potential tracer.

Dynamically consistent analysis of Galactic WN4b stars

Astronomy & Astrophysics
Context. Many Wolf-Rayet (WR) stars have optically thick winds that essentially cloak the hydrostatic layers of the underlying star. In these cases, traditional spectral analysis methods are plagued by degeneracies that make it difficult to constrain ...

The role of accretion efficiency, natal kicks, and angular momentum transport in the formation of the Gaia black holes

Astronomy & Astrophysics
Gaia has the potential to deliver several tens of new dormant black holes (BHs) with low-mass stellar companions (hereafter, Gaia BHs) in the upcoming fourth data release.
