ROSAT observations of 3C radio-loud sources
The 3CRR sample of radio galaxies and quasars has been cross-correlated with the ROSAT PSPC All-Sky Survey. About 25 per cent of the objects have been detected...
Double-peaked line profiles are commonly considered a hallmark of rotating discs, with the distance between the peaks a measure of the rotation velocity...
Rotating stellar populations in the Fornax dSph galaxy
We present a novel analysis of the internal kinematics of the Fornax dwarf spheroidal galaxy. Our results are based on the largest sample of spectroscopic data...
Rotation periods and photometric variability of rapidly rotating ultracool dwarfs
We used the optical and near-infrared imagers located on the Liverpool, the IAC80, and the William Herschel telescopes to monitor 18 M7-L9.5 dwarfs with the...
Rotation periods of late-type dwarf stars from time series high-resolution spectroscopy of chromospheric indicators
We determine rotation periods of a sample of 48 late F-type to mid-M dwarf stars using time series high-resolution spectroscopy of the Ca II H&K and H α...
Rotation rates, sizes and star formation efficiencies of a representative population of simulated disc galaxies
We examine the rotation rates, sizes and star formation (SF) efficiencies of a representative population of simulated disc galaxies extracted from the Galaxies...
Rotational broadening and Doppler tomography of the quiescent X-ray nova Centaurus X-4
We present high- and intermediate-resolution spectroscopy of the X-ray nova Centaurus X-4 during its quiescent phase. Our analysis of the absorption features...
Rotational fission of trans-Neptunian objects: the case of Haumea
We present several lines of evidence, based on different kinds of observations, and we conclude that it is likely that rotational fission has occurred for a...
Rotational modulation in A and F stars: magnetic stellar spots or convective core rotation?
The Kepler mission revealed a plethora of stellar variability in the light curves of many stars, some associated with magnetic activity or stellar oscillations...
