Non-conservative Mass Transfer as a Formation Channel for Gaia Black Hole System
Aleksandra Olejak, Jakub Klencki, Alejandro Vigna-Gomez +6
The detected Gaia systems hosting compact objects challenge standard models of binary star evolution. In particular, if the observed black hole (BH) systems evolved in isolation, t…
Sub-Snowline Formation of Gas-Giant Planets in Binary Systems
Ilay Kamai, Hagai B. Perets, Jakob Stegmann +1
Gas-giant planets are thought to require conditions beyond the water snow line to build solid cores efficiently. In close binary star systems, the companion's gravity additionally…
Orbital Eccentricity and Spin-Orbit Misalignment Are Evidence that Neutron Star-Black Hole Mergers Form through Triple Star Evolution
Jakob Stegmann, Jakub Klencki
There is growing evidence that a substantial fraction of the neutron star-black holes (NSBHs) detected through gravitational waves merge with non-zero eccentricity or large BH spin…
Supermassive black holes stripping a subgiant star down to its helium core: a new type of multi-messenger source for LISA
Aleksandra Olejak, Jakob Stegmann, Selma E. de Mink +3
Some stars orbiting supermassive black holes (SMBH) are expected to undergo a gravitational-wave (GW)-driven inspiral and initiate mass transfer on nearly circular orbits. However,…
Prompt stellar and binary black hole mergers in tight triples: Insights from chemically homogeneous evolution
Alejandro Vigna-Gómez, Evgeni Grishin, Jakob Stegmann +7
Short-period massive binary stars are predicted to undergo chemically homogeneous evolution (CHE), making them prime candidates for producing binary black holes (BBHs) that may mer…
The role of triple evolution in the formation of LISA double white dwarfs
Abinaya Swaruba Rajamuthukumar, Valeriya Korol, Jakob Stegmann +5
Galactic double white dwarfs will be prominent gravitational-wave sources for the Laser Interferometer Space Antenna (LISA). While previous studies have primarily focused on format…
Planet formation and long-term stability in a very eccentric stellar binary
Jakob Stegmann, Evgeni Grishin, Cole Johnston +4
Planets orbiting one of the two stars in a binary are vulnerable to gravitational perturbations from the other star. Particularly, highly eccentric companion stars risk disrupting…
