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...
Spectral variations of the 2.7 µm feature at sub-mm scales in Ryugu samples, within the ISAS Curation Facility
In December 2020, the Hayabusa2/JAXA mission returned to Earth ~5.4g of primitive material from the carbonaceous asteroid (162173) Ryugu. Since their return...
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...
Spectro-photometric studies of near-Earth asteroids using broad-band filters over the visible wavelengths
The spectro-photometric observations of asteroids provide the first information regarding their composition. They allow to classify the observed objects in...
