Importance of Tides for Periastron Precession in Eccentric Neutron Star - White Dwarf Binaries
Niharika Sravan, Francesca Valsecchi, Vassiliki Kalogera +1
Although not nearly as numerous as binaries with two white dwarfs, eccentric neutron star-white dwarf (NS-WD) binaries are important gravitational-wave (GW) sources for the next ge…
Introducing CAFein, a New Computational Tool for Stellar Pulsations and Dynamic Tides
Francesca Valsecchi, Will M. Farr, Bart Willems +2
Here we present CAFein, a new computational tool for investigating radiative dissipation of dynamic tides in close binaries and of non-adiabatic, non-radial stellar oscillations in…
Towards Synchronism Through Dynamic Tides in J0651: the "Antiresonance" Locking
Francesca Valsecchi, Will. M. Farr, Bart Willems +1
In recent years, the Extremely Low Mass White Dwarf (ELM WD) survey has quintupled the number of known close, detached double WD binaries (DWD). The tightest such DWD, SDSS J065133…
Constraining White Dwarf Masses Via Apsidal Precession in Eccentric Double White Dwarf Binaries
Francesca Valsecchi, Will M. Farr, Bart Willems +1
Galactic short period double white dwarfs (DWD) are guaranteed gravitational wave (GW) sources for the next generation of space-based interferometers sensitive to low-frequency GWs…
Tidally-Induced Apsidal Precession in Double White Dwarfs: a new mass measurement tool with LISA
Francesca Valsecchi, Will M. Farr, Bart Willems +2
Galactic interacting double white dwarfs (DWD) are guaranteed gravitational wave (GW) sources for the GW detector LISA, with more than 10^4 binaries expected to be detected over th…
Formation of the black-hole binary M33 X-7 via mass-exchange in a tight massive system
Francesca Valsecchi, Evert Glebbeek, Will M. Farr +5
M33 X-7 is among the most massive X-Ray binary stellar systems known, hosting a rapidly spinning 15.65 Msun black hole orbiting an underluminous 70 Msun Main Sequence companion in…
