Reframing the Wide Eccentric Binary Problem: Eccentricity as a Probe of Mass-transfer Physics
A. Parkosidis, S. Toonen, E. Laplace +1
Observations of wide post-interaction binaries show an unexpected feature; orbital eccentricity, which is not understood theoretically. A promising resolution to this long-standing…
Hubble as a Unique Discovery Engine of the Fate of Massive Stars and Black Hole Formation
Avishai Gilkis, Eva Laplace, Charles D. Kilpatrick +3
How stellar-mass black holes are formed is an open question in astrophysics, with very limited observational constraints. It is not known which types of stars are more likely to pr…
Hot blue progenitors of stellar-mass black holes
Avishai Gilkis, Eva Laplace, Maria Drout +3
While the connection between massive stars and supernova explosions is well established observationally, the link between massive stars and black hole formation remains elusive. So…
Rethinking mass transfer: a unified semianalytical framework for circular and eccentric binaries. II. Orbital evolution due to nonconservative mass transfer
A. Parkosidis, S. Toonen, E. Laplace +1
Although mass transfer (MT) has been studied primarily in circular binaries, observations show that it also occurs in eccentric systems. We investigate orbital evolution during non…
Rethinking mass transfer: a unified semi-analytical framework for circular and eccentric binaries. I. Orbital evolution due to conservative mass transfer
A. Parkosidis, S. Toonen, F. Dosopoulou +1
Mass transfer (MT) is a fundamental process in stellar evolution. While MT in circular orbits is well studied, observations indicate that it also occurs in eccentric ones, where th…
