Time-Resolved Spectroscopy of Ir-Geminorem at Quiescence
We present some preliminary results of a spectroscopic study of the cataclysmic system IR Gem at quiescence during two orbital periods. The spectra covered the...
Time-resolved UV spectroscopy of the accretion disk and wind in a super-Eddington black-hole X-ray transient
In October 2018, Swift announced the discovery of a new Galactic X-ray transient, Swift J1858. Just before Sun-angle constraints rendered the system...
Time-scales of Line-broadening Variability in OB Supergiants
Several works have recently shown that there is an important extra line-broadening (usually called macroturbulence) affecting the spectra of O and B Supergiants...
Timing Detection of Eclipsing Binary Planets and Transiting Extrasolar Moons
We investigate the improved detection of extrasolar planets around eclipsing binaries using eclipse minima timing and extrasolar moons around transiting planets...
Timing the accretion flow around accreting millisecond pulsars
At present, ten years after they were first discovered, ten accreting millisecond pulsars are known. I present a study of the aperiodic X-ray variability in...
TIP (Tenerife Infrared Polarimeter): a near IR full Stokes Polarimeter for the German Solar Telescopes at Observatorio del Teide
In this contribution, the main characteristics of the=20 Tenerife Infrared Polarimeter (TIP), recently built at the Instituto de Astrofísica de Canarias, to be...
