Optical microvariability (OM, small amplitude variations in time scales from minutes to hours) in radio-quiet quasars (RQQ) may be as frequent as in radio-loud...
Spectral Parameters Following Gaffey Method Of Near-earth Asteroids And Main Belt Objects
We have computed the Band Area Ratio (BAR) and Band I Center parameters, following the method by Cloutis et al. (1986) and Gaffey et al. (1993) for all the...
Spectral properties from XMM-Newton observation of Chandra Deep Field South sources
We present results of the X-ray spectral analysis of the ˜370 ksec deep survey obtained with XMM-Newton on the Chandra Deep Field South (CDFS). Using sample of...
Spectral properties of 2020 AV2, the first known asteroid orbiting inside Venus orbit
Recent numerical simulations (Greenstreet et al. 2012, Granvik et al. 2018) predicted the existence of a population of small bodies that is orbiting entirely...
Spectral properties of near-Earth asteroids on cometary orbits
We studied the spectral distributions of near-Earth asteroids on cometary orbits (NEACOs) in order to identify potential dormant or extinct comets among these...
Spectral synthesis of CARMENES M-type stars: stellar atmospheric parameters
We show our very first results regarding the stellar atmospheric parameter determinations (T_{eff} , log g, [Fe/H]) of M-type stars observed with CARMENES te...
Spectral transition of 4U 1608-522 during the undergoing 2010 outburst
Following the SuperAGILE detection of an X-ray burst from the neutron star transient and atoll source 4U 1608-522 (ATel #2461), on 3 March 2010 at 06:33:25 UT...
Spectrally resolved flares in the quiescent black hole V404 Cyg
We present a spectrophotometric study of short-term optical variability in the quiescent black hole X-ray transient V404 Cyg focusing on two nights of Hα...
