Spectrally dispersed non-redundant aperture-masking interferometry in the thermal infrared with LBTI/ALES
T. A. Stuber, J. M. Stone, J. W. Isbell +5
Non-redundant aperture-masking interferometry maximizes the angular resolution of a telescope by turning it into an interferometric array using pupil plane masks. If the interferen…
Upgrading LBTI/NOMIC with a quadruple annular groove phase mask and GeoSnap detector for imaging nearby, habitable-zone exoplanets
Kevin Wagner, Manny Montoya, Steve Ertel +32
The paper describes two upgrades to the Large Binocular Telescope Interferometer’s NOMIC camera—a quadruple annular groove phase mask coronagraph and a new Teledyne GeoSnap detecto…
Shocks, Winds, and a Torus: The Large Binocular Telescope Interferometer (LBTI) Resolves the Active Nucleus of NGC 4151
Jacob W. Isbell, Steve Ertel, Makoto Kishimoto +12
We present mid-infrared (MIR) observations of the Seyfert 1 galaxy NGC 4151 using the Large Binocular Telescope Interferometer (LBTI). We took open-loop Fizeau images with 66-104 m…
Interferometric Detection and Orbit Modeling of the Subcomponent in the Hot-dust System Tuc A: A Low-mass Star on an Eccentric Orbit in a Hierarchical-quintuple System
T. A. Stuber, A. Mérand, F. Kirchschlager +19
The system Tuc A is part of a hierarchical-quintuple system and is a prime target for studies of hot-exozodiacal dust, because a time-variable near-infrared excess has been de…
Wide Separation Planets In Time (WISPIT): Discovery of a Gap H Protoplanet WISPIT 2b with MagAO-X
Laird M. Close, Richelle F. van Capelleveen, Gabriel Weible +34
Excellent (<25 mas) H images of the star TYC 5709-354-1 led to the discovery of a rare H protoplanet. This star was discovered by the WISPIT survey to have a large multi-…
The HOSTS Survey: Suspected variable dust emission and constraints on companions around θ Boo
G. Garreau, D. Defrère, S. Ertel +23
During the HOSTS survey by the LBTI, an excess emission from the main sequence star θ Boo (F7V spectral type, 14.5pc distance) was observed. This excess indicates the presence of…
