The sites and mechanisms under which cosmic rays are accelerated up to relativistic energies are still under debate. Microquasar jets have been assessed as possible sources that may contribute to the total cosmic ray population, which is currently believed to be mainly originated in supernova remnants. We show preliminary results on the neutron

Context. Early theoretical works suggested that ultrahot Jupiters have inverted temperature-pressure (T–P) profiles in the presence of optical absorbers, such as TiO and VO. Recently, an inverted T–P profile of KELT-7b was detected, in agreement with the predictions. However, the diagnosis of T–P inversions has always been recognized to be a model

Context. The intracluster light (ICL) comprises stars that are not bound to individual galaxies within a galaxy cluster, and it provides insights into the cluster mass distribution, evolutionary history, and dynamical state. Aims. We study the viability of the intracluster stellar mass as a proxy for computing the total mass profiles of galaxy

Context. Recent observational results from asteroseismic studies show that an important fraction of solar-like stars do not present detectable stochastically excited acoustic oscillations. This non-detectability seems to correlate with a high rotation rate in the convective envelope and a high surface magnetic activity. At the same time, the

SUNRISE III is a balloon-borne solar observatory dedicated to investigating the physics governing the magnetism and dynamics in the lower solar atmosphere. The observatory is designed to operate in the stratosphere, at heights around 36 km (above 99% of Earth's atmosphere), to avoid image degradation due to turbulence in the Earth's lower

The vertical evolution of galactic discs is governed by the sub-structures within them. Several of these features, including bulges and kinematically distinct discs, are best studied in edge-on galaxies, as the viewing angle allows the easier separation of component light. For this work, we examined the diversity of kinematic sub-structure present
