Do Large Scale Jets Arise Only in Long Period Black Hole X-ray Novae?
In this brief note we remark that the four spatially resolved relativistic radio jets among the 14 dynamically confirmed black hole x-ray novae are all in...
It is very common in astrophysics that certain relevant parameters of the objects studied cannot be obtained directly from observations, but require numerical...
Do Neutron stars Or Black Holes Dominate The X-ray Binary Population Of The Youngest Starburst Galaxies?
We report on our year-long (2009-'10) campaign with the Chandra X-ray observatory, to capture the transient X-ray binary (XRB) population in the nearby...
Do R Coronae Borealis stars evolve from white dwarf mergers?
Phoenix spectra of C_2, CN and CO lines will provide oxygen isotopic abundance ratios (^16O/^17O/^18O) and CNO abundances for cool R Coronae Borealis (RCB)...
Do Starbursts Form Cored Density Profiles in Dwarf Galaxies?
It is widely accepted that starbursts can dramatically affect their host galaxies via feedback-driven outflows, especially for gas-rich dwarfs with shallow...
Do stellar and nebular abundances in the Cocoon nebula agree?
The Cocoon nebula is an apparently spherical Galactic HII region ionized by a single star (BD+46 3474). This nebula seems to be appropriate to investigate the...
A good alternative to traditional methods of passing on astronomical concepts is to use a 'collateral' story that catches the public's attention. It may also...
Do the Various Types of PNe Knots Differ in Terms of their Physical Properties? The case of NGC662
Years ago we have compiled all the available optical data in the literature to build a comprehensive classification of the low-ionization structures (LIS), as...
