Protocols for classically training quantum generative models on probability distributions
(American Physical Society, 5 October 2023)Quantum generative modeling (QGM) relies on preparing quantum states and generating samples from these states as hidden - or known - probability distributions. As distributions from some classes of quantum states (circuits) ... -
Imaging the warped dusty disk wind environment of SU Aurigae with MIRC-X
(EDP Sciences, 27 September 2023)Context. T Tauri stars are low-mass young stars whose disks provide the setting for planet formation, which is one of the most fundamental processes in astronomy. Yet the mechanisms of this are still poorly understood. SU ... -
The dusty circumstellar environment of Betelgeuse during the Great Dimming as seen by VLTI/MATISSE
(EDP Sciences, 30 June 2023)Context. The 'Great Dimming' of the prototypical red supergiant Betelgeuse, which occurred between December 2019 and April 2020, gives us unprecedented insight into the processes occurring on the stellar surface and in the ... -
Precise Age for the Binary Star System 12 Com in the Coma Berenices Cluster
(American Astronomical Society / IOP Publishing, 26 June 2023)We present measurements of the interferometrically resolved binary star system 12 Com and the single giant star 31 Com in the cluster Coma Berenices. 12 Com is a double-lined spectroscopic binary system consisting of a G7 ... -
The Great Dimming of the hypergiant star RW Cephei: CHARA Array images and spectral analysis
(IOP Publishing/American Astronomical Society, 31 July 2023)The cool hypergiant star RW Cephei is currently in a deep photometric minimum that began several years ago. This event bears a strong similarity to the Great Dimming of the red supergiant Betelgeuse that occurred in ...
