Herschel Observations of the T Cha Transition Disk: Constraining the Outer Disk Properties
Lucas A. Cieza, Johan Olofsson, Paul M. Harvey +7
T Cha is a nearby (d = 100 pc) transition disk known to have an optically thin gap separating optically thick inner and outer disk components. Huelamo et al. (2011) recently report…
Hot exozodiacal dust resolved around Vega with IOTA/IONIC
D. Defrère, O. Absil, J. -C. Augereau +10
Although debris discs have been detected around a significant number of main-sequence stars, only a few of them are known to harbour hot dust in their inner part where terrestrial…
Ruling out unresolved binaries in five transitional disks VLT/NACO: deep 2.12 and 1.75 μm narrow-band imaging
Silvia Vicente, Bruno Merın, Markus Hartung +8
Aims. We aim at detecting the presence of companions inside the inner hole/gap region of a sample of five well known transitional disks using spatially-resolved imaging in the near…
Low abundance, strong features: Window-dressing crystalline forsterite in the disk wall of HD 100546
G. D. Mulders, L. B. F. M. Waters, C. Dominik +10
Forsterite is one of the crystalline dust species that is often observed in protoplanetary disks and solar system comets. Being absent in the interstellar medium, it must be produc…
On the Evolution of Dust Mineralogy, From Protoplanetary Disks to Planetary Systems
Isa Oliveira, Johan Olofsson, Klaus M. Pontoppidan +3
Mineralogical studies of silicate features emitted by dust grains in protoplanetary disks and Solar System bodies can shed light on the progress of planet formation. The significan…
Warm dust resolved in the cold disk around T Cha with VLTI/AMBER
J. Olofsson, M. Benisty, J. -C. Augereau +12
The transition between massive Class II circumstellar disks and Class III debris disks, with dust residuals, has not yet been clearly understood. Disks are expected to dissipate wi…
