The Exozodiacal Dust Problem for Direct Observations of Exo-Earths
Aki Roberge,C. H. Chen,Rafael Millan-Gabet,Alycia J. Weinberger,Philip M. Hinz,Karl R. Stapelfeldt,Olivier Absil,Marc J. Kuchner,G. Bryden +8 more
TL;DR: In this article, the primary impact of exozodiacal dust on high-contrast direct imaging at optical wavelengths, such as would be performed with a coronagraph, is qualitatively assessed.
Spitzer Evidence for a Late-heavy Bombardment and the Formation of Ureilites in η Corvi at ~1 Gyr
Carey M. Lisse,Carey M. Lisse,Mark C. Wyatt,C. H. Chen,Andreas Morlok,Dan M. Watson,P. Manoj,Patrick D. Sheehan,Thayne Currie,Philippe Thébault,Michael L. Sitko +10 more
TL;DR: In this article, the authors analyzed Spitzer and NASA/IRTF 2-35 μm spectra of the warm, ~350 K circumstellar dust around the nearby MS star η Corvi (F2V, 1.4 ± 0.3 Gyr) and concluded that the parent body was a Kuiper Belt body or bodies which captured a large amount of early primitive material in the first megayears of the system's lifetime and preserved it in deep freeze at ~150 AU.
A Self-Consistent Model of the Circumstellar Debris Created by a Giant Hypervelocity Impact in the HD172555 System
Brandon C. Johnson,C. M. Lisse,C. H. Chen,H. J. Melosh,Mark C. Wyatt,Philippe Thébault,Wade G. Henning,Eric Gaidos,Linda T. Elkins-Tanton,John Bridges,Andreas Morlok +10 more
TL;DR: In this paper, the infrared excess in the Spitzer IRS spectra of HD 172555 suggests that there is more than 10^19 kg of sub-micron dust in the system.

The exceptionally large debris disk around γ ophiuchi
Kate Y. L. Su,George H. Rieke,Karl R. Stapelfeldt,Paul S. Smith,G. Bryden,C. H. Chen,David Trilling +6 more
TL;DR: In this article, the primary disk structure is inclined by 50° from the plane of the sky at a position angle of 55° ± 2°, and the observed sizes in the infrared and color temperatures indicate that evolution of the debris disks is influenced by multiple parameters in addition to the protoplanetary disk initial mass.
