Performance Analysis of the Asgard/NOTT Nulling Interferometer: Optimizing Observing Modes for High-contrast Detection
J. P. Scott, S. Ertel, T. A. Stuber +21
We evaluate the performance of three beam-combination schemes, single-Bracewell, asymmetric dual-Bracewell, and symmetric dual-Bracewell, for the forthcoming Asgard/NOTT nulling in…
Survival of very small carbonaceous dust grains in the inner-CGM of NGC 891 from JWST/MIRI MRS
Jérémy Chastenet, Ilse De Looze, Karl D. Gordon +26
We present new spectroscopic observations of the inner circumgalactic medium (CGM) of NGC 891 taken with the Mid-Infrared Imager/Medium Resolution Spectroscopy instrument onboard J…
MAJORS II: HCO+& HCN Abundances in W40
René Plume, David J. Eden, Malcolm J. Currie +34
We present observations of HCN and HCO J = in the central region of the W40 massive star forming region. The observations were taken as part of a p…
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 det…
Dust destruction by the supernova remnant forward shock in a turbulent interstellar medium
Tassilo Scheffler, Nina S. Sartorio, Florian Kirchschlager +3
Context. While supernova remnants (SNRs) are observed to produce up to 1 M of dust, the amount of dust destroyed by the forward shock (FS) is poorly constrained, raising th…
Close-in faint companions mimicking interferometric hot exozodiacal dust observations
Katsiaryna Tsishchankava, Florian Kirchschlager, Anton Krieger +2
Context: Interferometric observations of various nearby main-sequence stars show an unexpected infrared excess, raising the question of its origin. The two dominant interpretations…
