The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems III: Aperture Masking Interferometric Observations of the star HIP 65426 at 3.8 um
Shrishmoy Ray, Steph Sallum, Sasha Hinkley +121
We present aperture masking interferometry (AMI) observations of the star HIP 65426 at as a part of the JWST Direct Imaging Early Release Science (ERS) program obtai…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems IV: NIRISS Aperture Masking Interferometry Performance and Lessons Learned
Steph Sallum, Shrishmoy Ray, Jens Kammerer +120
We present a performance analysis for the aperture masking interferometry (AMI) mode on board the James Webb Space Telescope Near Infrared Imager and Slitless Spectrograph (JWST/NI…
MagAO-X and HST high-contrast imaging of the AS209 disk at H
Gabriele Cugno, Yifan Zhou, Thanawuth Thanathibodee +22
The detection of emission lines associated with accretion processes is a direct method for studying how and where gas giant planets form, how young planets interact with their nata…
JWST/NIRCam Coronagraphy of the Young Planet-hosting Debris Disk AU Microscopii
Kellen Lawson, Joshua E. Schlieder, Jarron M. Leisenring +20
High-contrast imaging of debris disk systems permits us to assess the composition and size distribution of circumstellar dust, to probe recent dynamical histories, and to directly…
Benchmarking Gaia DR3 Apsis with the Hyades and Pleiades open clusters
Wolfgang Brandner, Per Calissendorff, Taisiya Kopytova
The Gaia astrophysical parameters inference system (Apsis) provides astrophysical parameter estimates for several to 100s of millions of stars. We aim to benchmark Gaia DR3 Apsis.…
JWST/NIRCam discovery of the first Y+Y brown dwarf binary: WISE J033605.05014350.4
Per Calissendorff, Matthew De Furio, Michael Meyer +25
We report the discovery of the first brown dwarf binary system with a Y dwarf primary, WISE J033605.05014350.4, observed with NIRCam on JWST with the F150W and F480M filters. We…
Astrophysical properties of 600 bonafide single stars in the Hyades open cluster
Wolfgang Brandner, Per Calissendorff, Taisiya Kopytova
The determination of the astrophysical properties of stars remains challenging, and frequently relies on the application of stellar models. Stellar sequences in nearby open cluster…
