A black hole hiding in a binary star As material falls toward a black hole, it heats up and emits x-rays. Almost all black holes are discovered by this x-ray emission. Thompson et al. observed light from a giant star that is Doppler shifted, indicating an orbit around a binary companion. The companion object must weigh more than 2.6 solar masses, but it emits no light, including x-rays. This indicates the presence of a black hole that is not currently consuming any material. There may be a… Expand
Black Hole Mass Function of Coalescing Neutron Star Black Hole Binary Systems: The Prospect of Reconstruction with the Gravitational Wave Observations
The discovery of gravitational waves from compact objects coalescence opens a brand-new window to observe the universe. With more events being detected in the future, statistical examinations wouldExpand
Filling the Mass Gap: How Kilonova Observations Can Unveil the Nature of the Compact Object Merging with the Neutron Star
In this letter we focus on the peculiar case of a coalescing compact-object binary whose chirp mass is compatible both with a neutron star-neutron star and black hole-neutron star system, with theExpand
The Formation of a 70 M ⊙ Black Hole at High Metallicity
A 70Msun BH was discovered in Milky Way disk in a long period and almost circular detached binary system (LB-1) with a high metallicity 8Msun B star companion. Current consensus on the formation ofExpand
A naked-eye triple system with a nonaccreting black hole in the inner binary
Several dozen optical echelle spectra demonstrate that HR 6819 is a hierarchical triple. A classical Be star is in a wide orbit with an unconstrained period around an inner 40 d binary consisting ofExpand
A stripped helium star in the potential black hole binary LB-1
The recently claimed discovery of a massive ($M_\mathrm{BH}=68^{+11}_{-13}\,M_\odot$) black hole in the Galactic solar neighborhood has led to controversial discussions because it severely challengesExpand
A Strategy to Search for an Inner Binary Black Hole from the Motion of the Tertiary Star
There are several on-going projects to detect a number of stars orbiting around invisible objects. A fraction of them may be a triple system consisting of an inner binary black hole (BBH) and anExpand
Comment on “A noninteracting low-mass black hole–giant star binary system”
TLDR
If the red giant’s mass is ~1 solar mass, its companion can be a close binary consisting of two main-sequence stars, which would explain why no x-ray emission is detected from the system. Expand
Population Synthesis of Black Hole Binaries with Compact Star Companions
We perform a systematic study of merging black hole (BH) binaries with compact star (CS) companions, including black hole–white dwarf (BH–WD), black hole–neutron star (BH–NS), and black hole–blackExpand
Finding binary black holes in the Milky Way with LISA
We determine the main properties of the Galactic binary black hole (BBH) population detectable by LISA and strategies to distinguish them from the much more numerous white dwarf binaries. We simulateExpand
Distinguishing Binary Neutron Star from Neutron Star–Black Hole Mergers with Gravitational Waves
The gravitational-wave signal from the merger of two neutron stars cannot be easily differentiated from the signal produced by a comparable-mass mixed binary of a neutron star and a black hole.Expand
