Context. It is of broad interest for galaxy formation theory to carry out a full inventory of the numbers and properties of dwarf galaxies, both satellite and...

The transiting extrasolar planet XO-3b is remarkable, with a high mass and eccentric orbit. These unusual characteristics make it interesting to test whether...

Context. The existence of a maximum correlation angle (θ max ≳ 60°) in the two-point angular temperature correlations of cosmic microwave background (CMB)...

In this paper we deal with the problem of the generation of internal waves at the bottom of convective zone in solar-type stars, and with the transport process...

Aims: We investigate the data collected by the high-cadence microlensing surveys during the 2022 season in search of planetary signals appearing in the light...

We analyze more than 5000 days of high-quality Sun-as-a-star, radial velocity GOLF and photometric VIRGO/SPM helioseismic observations to extract precise...

Context. Quiescent solar prominence fine structures are typically modelled as density enhancements, called threads, which occupy a fraction of a longer magnetic...

We investigated the infrared (IR) dust emission from PN IC 418, using a detailed model controlled by a previous determination of the stellar properties and the...

We compare schematic modeling of spots and plage on the surface of cool dwarfs with Pleiades data to assess effects of magnetic activity on the strengths of the...
