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…
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…
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…
