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…
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…
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…
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,…
