HD 306414: Optical Counterpart to the Peculiar X-ray Transient IGR J11215-5952
We present high-resolution spectroscopy of HD 306414, optical counterpart to the hard X-ray transient IGR J11215-5952, an object belonging to the class of...
We compared the results from SigSpec and from the iterative-sine-wave fitting, considering an error range of 0.005d-1 in frequency (i.e., a width 3.4 times...
We present the results of a spectroscopic campaign on the early-type double-lined binary HD 64315. The radial velocity curve was calculated using a fit to model...
HD15082b, a short-period planet orbiting an A-star
Most of the known transiting extrasolar planets orbit slowly rotating F, G or K stars. In here we report on the detection of a transiting planet orbiting the...
He 2-147: A case in which the expansion parallax method fails
HST multi-epoch images and VLT integral-field, high resolution spectroscopy allowed us a robust determination of the 3-D geometry and orientation of the nebula...
It has been recently argued from a theoretical point of view that the interaction of some X-ray binary (XRB) jets with their environment will produce trails of...
