Phase-resolved X-ray spectroscopy of the Vela pulsar with NICER observations

PSR J0835-4510 (the Vela pulsar) is the best studied pulsar in the southern hemisphere given its high radio brightness and large glitch activity. However, its X-ray brightness is lower, making the study of its X-ray profile difficult. We aim to investigate the X-ray emission of t...

A giant magnetic eruption from the asymptotic-giant-branch star Mira A

Mass loss during the advanced evolutionary stages of low- and intermediate-mass stars is traditionally attributed to dust-driven winds, whereas the influence of magnetic fields remains poorly constrained. However, recent observations show massive directional mass ejections from t...

Resolving the heart of the Wolf-Rayet binary Apep with ALMA

The Wolf-Rayet (WR) phase is a critical stage in the evolution of massive stars. During this phase, stars experience a significant loss of mass in the form of fast winds that are enriched with heavy elements. There are only a few WR binaries in the Galaxy, with being a truly exce...
