Host galaxies, BH Masses and Eddington Ratio of Radio-Loud AGNs
We compare the host galaxies properties of BL Lac objects with those of radio loud quasars (RLQs) imaged by the WFPC2 on board of HST. The considered objects (z
Hot Jupiters around M dwarfs. A sensitivity analysis of the WFCAM Transit Survey
The WFCAM Transit Survey (WTS) is a near-infrared transit survey running on the United Kingdom Infrared Telescope (UKIRT). We conduct Monte Carlo transit...
Hot spiral structure in the accretion disk of the dwarf nova IP Pegasi
We present observational evidence of high-temperature spiral structure on the accretion disk of the dwarf nova IP Peg during outburst. The Doppler tomogram of...
The Gaia-ESO Survey (GES) is a large public spectroscopic survey that has collected spectra of about 100,000 stars. The survey provides not only the reduced...
Hot stars in young massive clusters: Mapping the current Galactic metallicity
Young Massive Clusters (YMCs) with ages 6 Myr are ideal tools for mapping the current chemical abundances in the Galactic disk for several reasons. First of...
Hot Subdwarfs: Magnetic, Oscillatory and Other Physical Properties
Hot subdwarf stars (hot sds) are blue subluminous objects. Only a few determinations are available to date regarding the study of such aspects as rotation...
