Exo-zodi modelling for the Large Binocular Telescope Interferometer
Grant M. Kennedy, Mark C. Wyatt, Vanessa Bailey +18
Habitable zone dust levels are a key unknown that must be understood to ensure the success of future space missions to image Earth analogues around nearby stars. Current detection…
Maximizing the ExoEarth Candidate Yield from a Future Direct Imaging Mission
Christopher C. Stark, Aki Roberge, Avi Mandell +1
ExoEarth yield is a critical science metric for future exoplanet imaging missions. Here we estimate exoEarth candidate yield using single visit completeness for a variety of missio…
Volatile-Rich Circumstellar Gas in the Unusual 49 Ceti Debris Disk
Aki Roberge, Barry Y. Welsh, Inga Kamp +2
We present Hubble Space Telescope STIS far-UV spectra of the edge-on disk around 49 Ceti, one of the very few debris disks showing sub-mm CO emission. Many atomic absorption lines…
Constraining the structure of the transition disk HD 135344B (SAO 206462) by simultaneous modeling of multiwavelength gas and dust observations
A. Carmona, C. Pinte, W. F. Thi +14
HD 135344B is an accreting (pre-) transition disk that displays the emission of warm CO extending tens of AU inside its 30 AU dust cavity. We used the dust radiative transfer code…
Molecular Gas Clumps from the Destruction of Icy Bodies in the Pictoris Debris Disk
W. R. F. Dent, M. C. Wyatt, A. Roberge +11
Many stars are surrounded by disks of dusty debris formed in the collisions of asteroids, comets and dwarf planets. But is gas also released in such events? Observations at submm w…
How dusty is alpha Centauri? Excess or non-excess over the infrared photospheres of main-sequence stars
J. Wiegert, R. Liseau, P. Thébault +19
[Abridged] Debris discs around main-sequence stars indicate the presence of larger rocky bodies. The components of the nearby binary aCentauri have higher than solar metallicities,…
