The archaeological World Heritage Site of Hegra (Mada´in Salih, Al-Hijr), in Saudi Arabia, is often considered the southern capital of the Nabataean Kingdom. Positioned just northeast of the AlUla Valley (where ancient Dadan is located), the Nabataeans recreated several aspects of their northern capital, Petra. They carved more than 130 tombs into

Context. The physical parameters of the sunspot are not fully understood, especially the height dependence of the magnetic field. So far, it is also an open question as to which heights the He I 10 830 Å spectral line is formed at. Aims: Our aim is to investigate the magnetic and dynamical properties in the atmosphere above a sunspot, from the

TOI-1518b, a hot Jupiter around a late A-type star, is one of the few planetary systems that transit the edge of the stellar surface (the impact parameter b ~ 0.9) among hot Jupiters around hot stars (Cabot et al. 2021, AJ, 162, 218). The high rotation speed of the host star (~85 km s -1) and the nearly polar orbit of the planet (~120 ○) may cause
