The eclipsing binary millisecond pulsar PSR B1744-24A - possible test for a magnetic braking mechanism
Ene Ergma, Marek J. Sarna
As presented by Nice et al. (2000), long-term timing of the eclipsing binary PSR B1744-24A shows that the orbital period of this system decreases with a time-scale of only ~ 200 My…

An evolutionary scenario for the U Scorpii
Ene Ergma, Jelena Gerskevits, Marek J. Sarna
We perform evolutionary calculations of binary stars to find progenitors of systems with parameters similar to the recurrent novae U Sco. We show that a U Sco type-system may be fo…
