A short answer to critics of our article "Eppur si espande" [arXiv:astro-ph/0612155]
Marek A. Abramowicz, Stanislaw Bajtlik, Jean-Pierre Lasota +1
Recently [arXiv:astro-ph/0612155] we presented a formal mathematical proof that, contrary to a widespread misconception, cosmological expansion cannot be understood as the motion o…
Radio-loudness of Active Galaxies and the Black Hole Evolution
M. Sikora, L. Stawarz, J. -P. Lasota
Active galactic nuclei (AGNs) form two distinct sequences on the radio-loudness -- Eddington-ratio plane. The `upper' sequence contains radio selected AGNs, the `lower' sequence is…
ADAFs, accretion discs and outbursts in compact binaries
Jean-Pierre Lasota
I discuss the status of the Soft X-ray Transient model. First, I discuss and then compare with observations the assumption that the geometrically thin disc evaporates into an ADAF.…
Spectra of accretion discs around white dwarfs
Irit Idan, Jean-Pierre Lasota, Jean-Marie Hameury +1
We present spectra of accretion discs around white-dwarfs calculated with an improved and updated version of the Shaviv & Wehrse (1991) model. The new version includes line opaciti…
Evolutionary models of short-period soft X-ray transients: comparison with observations
L. Yungelson, J. -P. Lasota
We consider evolutionary models for the population of short-period (<10 hr) low-mass black-hole binaries (LMBHBs) and compare them with observations of soft X-ray transients (SXTs)…
Stability of helium accretion discs in ultracompact binaries
Jean-Pierre Lasota, Guillaume Dubus, Katarzyna Kruk
Stellar companions of accreting neutron stars in ultra compact X-ray binaries (UCXBs) are hydrogen-deficient. Their helium or C/O accretion discs are strongly X-ray irradiated. Bot…
