Understanding selection effects in observed samples of cataclysmic variables (2006)
Pretorius, Magaretha L., Knigge, Christian, Kolb, Ulrich
Large differences between the properties of the known sample of cataclysmic variable stars (CVs) and the predictions of the theory of binary star evolution have long been recognised. However, because...

We have evolved over a hundred thousand binary systems using a full stellar evolution code in order to investigate the feeding of any IMBHs in gobular clusters and their claims as ultraluminous X-ray...

Downes, Ronald A., Webbink, Ronald F., Shara, Michael M., Ritter, Hans, Kolb, Ulrich, Duerbeck, Hilmar W.
The Catalog and Atlas of Cataclysmic Variables has been a staple of the CV community for over 10 years. The catalog has grown from 751 CVs in 1993 to 1600 CVs at present. The catalog became a...
Discovery and modelling of disc precession in the M31 X-ray binary Bo 158 (2006)
Barnard, Robin, Foulkes, S. B., Haswell, C. A., Kolb, Ulrich, Osborne, J. P., Murray, J. R.
The low mass X-ray binary (LMXB) associated with the M31 globular cluster Bo 158 is known to exhibit intensity dips on a ~2.78 hr period. This is due to obscuration of the X-ray source on the orbital...

Rapid rotation of ultra-li-depleted halo stars and their association with blue stragglers (2002)
Ryan, Sean G., Gregory, Scott G., Kolb, Ulrich, Beers, Timothy C., Kajino, Toshitaka
Observations of 18 halo main-sequence turnoff stars, four of which are extremely deficient in Li, show that three of the Li-poor ones have substantial line broadening. We attribute this to stellar...

Nova-induced mass transfer variations (2001)
Kolb, Ulrich, Rappaport, Saul, Schenker, Klaus, Howell, Steve
We investigate variations of the mass transfer rate in cataclysmic variables (CVs) that are induced by nova outbursts. The ejection of nova shells leads to a spread of transfer rates in systems with...

The violent past of Cygnus X-2 (2000)
Kolb, Ulrich, Davies, Melvyn, King, Andrew, Ritter, Hans
Cygnus X-2 appears to be the descendant of an intermediate-mass X-ray binary (IMXB). Using Mazzitelli's (1989) stellar code we compute detailed evolutionary sequences for the system and find that its...
Brown Dwarfs and the Cataclysmic Variable Period Minimum (1999)
Kolb, Ulrich, Baraffe, Isabelle
Using improved, up-to-date stellar input physics tested against observations of low-mass stars and brown dwarfs we calculate the secular evolution of low-mass donor cataclysmic variables (CVs),...
Secondary Stars in CVs: The Theoretical Perspective (1999)
Kolb, Ulrich, Baraffe, Isabelle
We apply the new generation of theoretical models of low-mass stars to secondaries in CVs, focussing on systems above the period gap. The models confirm that the spectral type should be a good...

Using improved, up-to-date stellar input physics tested against observations of low-mass stars and brown dwarfs we calculate the secular evolution of low-mass donor CVs, including those which form...
Binary evolution with relativistic jets (1998)
Relativistic jets can extract mass-energy from a black hole. In semi-detached black hole binaries the jet ejection process constitutes a `consequential angular momentum loss' (CAML) process. The...
Supernova Kicks, Magnetic Braking, and Neutron-Star Binaries (1998)
Kalogera, Vassiliki, Kolb, Ulrich, King, Andrew
We consider the formation of low-mass X-ray binaries containing accreting neutron stars via the helium-star supernova channel. The predicted relative number of short-period transients provides a...
Properties of discontinuous and nova-amplified mass transfer in CVs (1998)
Schenker, Klaus, Kolb, Ulrich, Ritter, Hans
We investigate the effects of discontinuous mass loss in recurrent outburst events on the long-term evolution of cataclysmic variables (CVs). Similarly we consider the effects of frictional angular...
Soft X-Ray Transients in the Hertzsprung Gap (1998)
We apply the disc instability model for soft X-ray transients to identify system parameters along evolutionary sequences of black hole X-ray binaries (BHXBs) that are consistent with transient...
CV and LMXB Population Synthesis (1997)
I discuss population synthesis methods in the context of low-mass compact binaries. Two examples, both constraining the largely unknown strength of orbital angular momentum losses, illustrate the...
The Transient Nature of GRO J1655-40 and its Evolutionary State (1997)
Kolb, Ulrich, King, Andrew, Ritter, Hans, Frank, Juhan
We consider the evolutionary state of the black-hole X-ray source GRO J1655-40 in the context of its transient nature. Recent optical observations show that the donor in GRO J1655-40 is an...
