Observation of Gravitational Waves from Two Neutron Star–Black Hole Coalescences

We report the observation of gravitational waves from two compact binary coalescences in LIGO’s and Virgo’s third observing run with properties consistent with neutron star–black hole (NSBH) binaries. The two events are named GW200105_162426 and GW200115_042309, abbreviated as GW200105 and GW200115; the first was observed by LIGO Livingston and Virgo and the second by all three LIGO–Virgo detectors. The source of GW200105 has component masses 8.9 +1.2/-1.5 and 1.9 +0.3/-0.2 M_S , whereas the source of GW200115 has component masses 5.7 +1.8/-2.1 and 1.5 +0.7/-0.3 M_S (all measurements quoted at the 90% credible level). The probability that the secondary’s mass is below the maximal mass of a neutron star is 89%–96% and 87%–98%, respectively, for GW200105 and GW200115, with the ranges arising from different astrophysical assumptions.


Gravitational Waves Reveal Black Hole - Neutron Star Mergers

Astrophysicists detect first black hole-neutron star mergers

The New York Times

A Black Hole Feasted on a Neutron Star. 10 Days Later, It Happened Again.

Astronomers had long suspected that collisions between black holes and dead stars occurred, but they had no evidence until a pair of recent detections.

Hi,

danke für den Hinweis.

Mir fällt gerade auf, dass Gravitationswellen eigentlich der einzige direkte Nachweis von Schwarzen Löchern ist.

Alles andere kann auch durch eine sehr kompakte Masse, was immer das dann ist, die nicht unbedingt ein schwarzes Loch sein muss, erklärt werden.
Es ist ein direkter Nachweis, andere Methoden sind nur indirekt.

Gruß
Peter
