Resolving the Young 2 Cygni Run-away Star into a Binary using iLocater
Justin R. Crepp, Jonathan Crass, Andrew J. Bechter +30
Precision radial velocity (RV) spectrographs that use adaptive optics (AO) show promise to advance telescope observing capabilities beyond those of seeing-limited designs. We are b…
The Roman coronagraph community participation program: observation planning
Schuyler G. Wolff, Jason Wang, Karl Stapelfeldt +18
The Coronagraphic Instrument onboard the Nancy Grace Roman Space Telescope is an important stepping stone towards the characterization of habitable, rocky exoplanets. In a technolo…
The grazing angle icy protoplanetary disk PDS 453
Laurine Martinien, François Ménard, Gaspard Duchêne +12
PDS 453 is a rare highly inclined disk where the stellar photosphere is seen at grazing incidence on the disk surface. Our goal is take advantage of this geometry to constrain the…
JWST imaging of edge-on protoplanetary disks. III. Drastic morphological transformation across the mid-infrared in Oph163131
Marion Villenave, Karl R. Stapelfeldt, Gaspard Duchene +6
We present JWST broadband images of the highly inclined protoplanetary disk SSTc2d J163131.2-242627 (Oph163131) from 2.0 to 21m. The images show a remarkable evolution in disk s…
A Survey of Protoplanetary Disks Using the Keck/NIRC2 Vortex Coronagraph
Nicole L. Wallack, Jean-Baptiste Ruffio, Garreth Ruane +34
Recent Atacama Large Millimeter/submillimeter Array (ALMA) observations of protoplanetary disks in the millimeter continuum have shown a variety of radial gaps, cavities, and spira…
MIRI MRS Observations of Beta Pictoris II. The Spectroscopic Case for a Recent Giant Collision
Christine H. Chen, Cicero X. Lu, Kadin Worthen +17
Modeling observations of the archetypal debris disk around Pic, obtained in 2023 January with the MIRI MRS on board JWST, reveals significant differences compared with that obt…
