Context. Solar active regions show a wide variety of oscillatory phenomena. The presence of the magnetic field leads to the appearance of several wave modes...
Aims: We analyse unpublished Spitzer observations of the thermal phase-curve of WASP-121 b, a benchmark ultra-hot Jupiter. Methods: We adopted the wavelet pixel...
Star formation in IC1396: Kinematics and subcluster structure revealed by Gaia
Aims: We investigate the star formation history of the IC1396 region by studying its kinematics and completing the population census. Methods: We used...
Star Formation in the Local Universe from the CALIFA Sample. II. Activation and Quenching Mechanisms in Bulges, Bars, and Disks
We estimate the current extinction-corrected Hα star formation rate (SFR) of the different morphological components that shape galaxies (bulges, bars, and disks...
Star tracking for pointing determination of Imaging Atmospheric Cherenkov Telescopes. Application to the Large-Sized Telescope of the Cherenkov Telescope Array
We present a novel approach to the determination of the pointing of Imaging Atmospheric Cherenkov Telescopes (IACTs) using the trajectories of the stars in...
Star-forming Regions in the Irregular Galaxy NGC 4449: Determination of Their Integrated Parameters
We present a study of the H II regions in the central area of the giant irregular galaxy NGC 4449 based on observations taken on the William Herschel Telescope...
STARE operations experience and its data quality control
The STARE instrument was the first to detect the transits of an extrasolar planet in 1999. To date it has performed one of the longest running searches for...
Stellar activity and rotation of the planet host Kepler-17 from long-term space-borne photometry
Context. The study of young Sun-like stars is fundamental to understanding the magnetic activity and rotational evolution of the Sun. Space-borne photometry by...
Stellar activity consequence on the retrieved transmission spectra through chromatic Rossiter-McLaughlin observations
Mostly multiband photometric transit observations have been used so far to retrieve broadband transmission spectra of transiting exoplanets in order to study...
