The James Webb Space Telescope Mission
Jonathan P. Gardner, John C. Mather, Randy Abbott +1004
Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized…
Debris Disk Color with the Hubble Space Telescope
Bin B. Ren, Isabel Rebollido, Élodie Choquet +14
Multi-wavelength scattered light imaging of debris disks may inform dust properties including typical size and mineral composition. Existing studies have investigated a small set o…
Cosmic-Ray-Related Signals from Detectors in Space: the Spitzer/IRAC Si:As IBC Devices
Brendan Hagan, George Rieke, Ori D. Fox +4
We evaluate the hit rate of cosmic rays and their daughter particles on the Si:As IBC detectors in the IRAC instrument on the Spitzer Space Telescope. The hit rate follows the ambi…
A Layered Debris Disk around M Star TWA 7 in Scattered Light
Bin Ren, Élodie Choquet, Marshall D. Perrin +15
We have obtained Hubble Space Telescope (HST) coronagraphic observations of the circumstellar disk around M star TWA 7 using the STIS instrument in visible light. Together with arc…
An Exo-Kuiper Belt and An Extended Halo around HD 191089 in Scattered Light
Bin Ren, Élodie Choquet, Marshall D. Perrin +70
We have obtained Hubble Space Telescope STIS and NICMOS, and Gemini/GPI scattered light images of the HD 191089 debris disk. We identify two spatial components: a ring resembling K…
ALICE Data Release: A revaluation of HST-NICMOS coronagraphic images
J. B. Hagan, E. Choquet, R. Soummer +1
The Hubble Space Telescope (HST) NICMOS instrument has been used from 1997 to 2008 to perform coronagraphic observations of about 400 targets. Most of them were part of surveys loo…
HD 104860 and HD 192758: two debris disks newly imaged in scattered-light with HST
É. Choquet, G. Bryden, M. D. Perrin +15
We present the first scattered-light images of two debris disks around the F8 star HD 104860 and the F0V star HD 192758, respectively and pc away. We detected the…
First scattered-light images of the gas-rich debris disk around 49 Ceti
É. Choquet, J. Milli, Z. Wahhaj +31
We present the first scattered-light images of the debris disk around 49 ceti, a ~40 Myr A1 main sequence star at 59 pc, famous for hosting two massive dust belts as well as large…
First images of debris disks around TWA 7, TWA 25, HD 35650, and HD 377
Élodie Choquet, Marshall D. Perrin, Christine H. Chen +15
We present the first images of four debris disks observed in scattered light around the young (4--250 Myr old) M dwarfs TWA 7 and TWA 25, the K6 star HD 35650, and the G2 star HD 3…
Archival Legacy Investigations of Circumstellar Environments (ALICE): Statistical assessment of point source detections
É. Choquet, L. Pueyo, R. Soummer +5
The ALICE program, for Archival Legacy Investigation of Circumstellar Environment, is currently conducting a virtual survey of about 400 stars, by re-analyzing the HST-NICMOS coron…
Characterizing the Atmospheres of the HR8799 Planets with HST/WFC3
Abhijith Rajan, Travis S. Barman, Remi Soummer +7
We present results from a Hubble Space Telescope (HST) program characterizing the atmospheres of the outer two planets, in the HR8799 system. The images were taken over 15 orbits i…
Archival Legacy Investigations of Circumstellar Environments: Overview and First Results
Élodie Choquet, Laurent Pueyo, J. Brendan Hagan +12
We are currently conducting a comprehensive and consistent re-processing of archival HST-NICMOS coronagraphic surveys using advanced PSF subtraction methods, entitled the Archival…
Five Debris Disks Newly Revealed in Scattered Light from the HST NICMOS Archive
Rémi Soummer, Marshall D. Perrin, Laurent Pueyo +12
We have spatially resolved five debris disks (HD 30447, HD 35841, HD 141943, HD 191089, and HD 202917) for the first time in near-infrared scattered light by reanalyzing archival H…
