The globular cluster NGC 6388: -Newton and observations
A. A. Nucita, F. De Paolis, G. Ingrosso +2
By studying the optical brightness surface density of the globular cluster NGC 6388, it has been recently proposed that it harbors a central intermediate-mass black hole with mass…
The Orbital Period of the Wolf-Rayet Binary IC 10 X-1; Dynamic Evidence that the Compact Object is a Black Hole
A. H. Prestwich, R. Kilgard, P. A. Crowther +6
IC 10 X-1 is a bright (Lx=10^38 ergs/s) variable X-ray source in the local group starburst galaxy IC 10. The most plausible optical counterpart is a luminous Wolf-Rayet star, makin…
XMM observation of 1RXS J180431.1-273932: a new M-type X-ray binary with a 494 s-pulse period neutron star?
A. A. Nucita, S. Carpano, M. Guainazzi
Low-mass X-ray binaries are binary systems composed of a compact object and a low-mass star. Recently, a new class of these systems, known as symbiotic -ray binaries (with a neu…
An ultraluminous supersoft source with a 4 hour modulation in NGC 4631
S. Carpano, A. M. T. Pollock, A. R. King +2
Context. Supersoft X-ray sources (SSSs) are characterised by very low temperatures (< 100 eV). Classical SSSs have bolometric luminosities in the range of 10^36-10^38 erg/s and are…
On the optical counterpart of NGC300 X-1 and the global Wolf-Rayet content of NGC300
Paul A Crowther, S. Carpano, L. J. Hadfield +1
(Conext:) Surveys of Wolf-Rayet (WR) populations in nearby galaxies provide tests of evolutionary models plus Type Ib/c supernova progenitors. This spectroscopic study complements…
A 33 hour period for the Wolf-Rayet/black hole X-ray binary candidate NGC 300 X-1
S. Carpano, A. M. T. Pollock, A. Prestwich +4
Context. NGC 300 X-1 is the second extragalactic candidate, after IC 10 X-1, in the rare class of Wolf-Rayet/compact object X-ray binary systems exemplified in the Galaxy by Cyg X-…
