Betelgeuse scope: Single-mode-fibers-assisted optical interferometer design for dedicated stellar activity monitoring
Narsireddy Anugu, Katie M. Morzinski, Josh Eisner +12
Betelgeuse has gone through a sudden shift in its brightness and dimmed mysteriously. This is likely caused by a hot blob of plasma ejected from Betelgeuse and then cooled to obscu…
First L band detection of hot exozodiacal dust with VLTI/MATISSE
Florian Kirchschlager, Steve Ertel, Sebastian Wolf +2
For the first time we observed the emission of hot exozodiacal dust in L band. We used the new instrument MATISSE at the Very Large Telescope Interferometer to detect the hot dust…
Implementing multi-wavelength fringe tracking for the Large Binocular Telescope Interferometer's phase sensor, PHASECam
Erin R. Maier, Phil Hinz, Denis Defrère +5
PHASECam is the fringe tracker for the Large Binocular Telescope Interferometer (LBTI). It is a near-infrared camera which is used to measure both tip/tilt and fringe phase variati…
On the Chemical Abundance of HR 8799 and the Planet c
Ji Wang, Jason Wang, Bo Ma +10
Comparing chemical abundances of a planet and the host star reveals the origin and formation path. Stellar abundance is measured with high-resolution spectroscopy. Planet abundance…
First Images of the Protoplanetary Disk Around PDS 201
Kevin Wagner, Jordan Stone, Ruobing Dong +11
Scattered light imaging has revealed nearly a dozen circumstellar disks around young Herbig Ae/Be starsenabling studies of structures in the upper disk layers as potential signs…
Exocomets: A spectroscopic survey
I. Rebollido, C. Eiroa, B. Montesinos +18
While exoplanets are now routinely detected, the detection of small bodies in extrasolar systems remains challenging. Since the discovery of sporadic events interpreted as exocomet…
The HOSTS survey for exozodiacal dust: Observational results from the complete survey
Steve Ertel, Denis Defrère, Philip M. Hinz +43
The Large Binocular Telescope Interferometer (LBTI) enables nulling interferometric observations across the N band (8 to 13 um) to suppress a star's bright light and probe for fain…
Rapid grain growth in post-AGB disc systems from far-infrared and sub-millimetre photometry
P. Scicluna, F. Kemper, A. Trejo +3
The timescales on which astronomical dust grows remain poorly understood, with important consequences for our understanding of processes like circumstellar disk evolution and plane…
