摘要

上下文。最近天体测量学发现了附近(590pc)大质量(33m⊙)休眠黑洞候选盖亚BH3,这提供了利用光学干涉测量技术从伴星角度分辨黑洞的可能性。我们的目的是探测盖亚BH3近距离环境中由吸积引起的近红外K波段发射。盖亚BH3是用重力仪器观测的,使用了VLT干涉仪的4个8米单位望远镜。我们使用CANDID, PMOIRED和exoGravity工具在干涉测量数据中搜索黑洞发射的特征。目前Gaia BH3系统的距离为18 mas,可以很好地利用重力进行角度分辨。我们没有探测到黑洞与伴星的辐射在Δm = 6.8等的对比水平,即在K波段fBH/f - fBH−16 W m−2 μm−1。此外,我们没有探测到黑洞在氢Brγ线的发射。盖亚BH3黑洞的近红外辐射未被探测到,这表明它对巨大恒星风的吸积目前最多以非常低的速度发生。这与先前在以平流为主的吸积流的Eddington比率上得到的fEdd−7的极限是一致的。当伴星在2030年左右接近近地星时,借助引力进行更深入的观测可能能够探测到黑洞。

VLTI/GRAVITY upper limit on near-infrared emission from the nearby 33 M⊙ black hole Gaia BH3
Context. The recent astrometric discovery of the nearby (590 pc) massive (33 M) dormant black hole candidate Gaia BH3 offers the possibility to angularly resolve the black hole from its companion star by using optical interferometry.Aims. Our aim is to detect emission in the near-infrared K band from the close-in environment of Gaia BH3 caused by accretion.Methods. Gaia BH3 was observed with the GRAVITY instrument using the four 8-meter Unit Telescopes of the VLT Interferometer. We searched for the signature of emission from the black hole in the interferometric data using the CANDID, PMOIRED, and exoGravity tools.Results. With a present separation of 18 mas, the Gaia BH3 system can be well resolved angularly by GRAVITY. We did not detect emission from the black hole at a contrast level of Δm = 6.8 mag with respect to the companion star, that is, fBH/f < 0.2%. This corresponds to an upper limit on the continuum flux density of fBH < 1.9 × 10−16 W m−2 μm−1 in the K band. In addition, we did not detect emission from the black hole in the hydrogen Brγ line.Conclusions. The non-detection of near-infrared emission from the black hole in Gaia BH3 indicates that its accretion of the giant star wind is presently occurring at most at a very low rate. This is consistent with the limit of fEdd < 4.9 × 10−7 derived previously on the Eddington ratio for an advection-dominated accretion flow. Deeper observations with GRAVITY may be able to detect the black hole as the companion star approaches periastron around 2030.
