The Near Infrared Imager and Slitless Spectrograph for the James Webb Space Telescope -- IV. Aperture Masking Interferometry
Anand Sivaramakrishnan, Peter Tuthill, James P. Lloyd +36
The James Webb Space Telescope's Near Infrared Imager and Slitless Spectrograph (JWST-NIRISS) flies a 7-hole non-redundant mask (NRM), the first such interferometer in space, opera…
The Near Infrared Imager and Slitless Spectrograph for JWST -- V. Kernel Phase Imaging and Data Analysis
Jens Kammerer, Rachel A. Cooper, Thomas Vandal +26
Kernel phase imaging (KPI) enables the direct detection of substellar companions and circumstellar dust close to and below the classical (Rayleigh) diffraction limit. We present a…
Nested Dust Shells around the Wolf-Rayet Binary WR 140 observed with JWST
Ryan M. Lau, Matthew J. Hankins, Yinuo Han +29
Massive colliding-wind binaries that host a Wolf-Rayet (WR) star present a potentially important source of dust and chemical enrichment in the interstellar medium (ISM). However, t…
3D orbital architecture of a dwarf binary system and its planetary companion
Salvador Curiel, Gisela N. Ortiz-León, Amy J. Mioduszewski +2
Because of the diversity of stellar masses and orbital sizes of binary systems, and the complex interaction between star-star, star-planet and planet-planet, it has been difficult…
Probing the innermost region of the AU~Microscopii debris disk
A. Gallenne, C. Desgrange, J. Milli +7
AU Mic is a young and nearby M-dwarf star harbouring a circumstellar debris disk and one recently discovered planet on an 8d orbit. Large-scale structures within the disk were also…
The dusty heart of Circinus: I. Imaging the circumnuclear dust in N-band
Jacob W. Isbell, Klaus Meisenheimer, Jörg-Uwe Pott +28
Active galactic nuclei play a key role in the evolution of galaxies, but their inner workings and physical connection to the host are poorly understood due to a lack of angular res…
The outer orbit of the high-mass stellar triple system Herschel 36 determined with the VLTI
J. Sanchez-Bermudez, C. A. Hummel, J. Díaz-López +8
Multiplicity is a ubiquitous characteristic of massive stars. Multiple systems offer us a unique observational constraint on the formation of high-mass systems. Herschel 36 A is a…
Two Rings and a Marginally Resolved, 5 AU, Disk Around LkCa 15 Identified Via Near Infrared Sparse Aperture Masking Interferometry
Dori Blakely, Logan Francis, Doug Johnstone +10
Sparse aperture masking interferometry (SAM) is a high resolution observing technique that allows for imaging at and beyond a telescope's diffraction limit. The technique is ideal…
A dusty veil shading Betelgeuse during its Great Dimming
M. Montargès, E. Cannon, E. Lagadec +24
Red supergiants are the most common final evolutionary stage of stars that have initial masses between 8 and 35 times that of the Sun. During this stage, which lasts roughly 100,00…
