The effect of triples on the Chemically Homogeneous Evolution Channel for producing Gravitational Wave Sources
Silvia A. Popa, Selma E. de Mink, Stephen Justham +3
Despite the growing number of gravitational-wave (GW) detections, the formation of merging binary black holes (BBHs) is still debated. One of the proposed formation channels is Che…
Mass and spin properties of black-hole mergers reveal formation in triples
Jakob Stegmann, Aleksandra Olejak
Deciphering the formation channels of the observed binary black hole mergers remains a central open problem in gravitational-wave astronomy. With hundreds of detections, the inferr…
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…
Close Encounters of Wide Binaries Induced by the Galactic Tide: Implications for Stellar Mergers and Gravitational-Wave Sources
Jakob Stegmann, Alejandro Vigna-Gómez, Antti Rantala +6
A substantial fraction of stars can be found in wide binaries with projected separations between and . In the standard lore of binary physics, these would…
Stupendously Large Black Hole Coalescence and Hubble Tensions
Earl Patrick Bellinger, Jakob Stegmann, Tom Wagg
Local and distant measurements of the Hubble constant are in significant tension: local measurements of the Hubble constant appear to show a Universe that is significantly contract…
