A Major Asymmetric Dust Trap in a Transition Disk
Nienke van der Marel, Ewine F. van Dishoeck, Simon Bruderer +9
The statistics of discovered exoplanets suggest that planets form efficiently. However, there are fundamental unsolved problems, such as excessive inward drift of particles in prot…
Herschel Observations of Gas and Dust in the Unusual 49 Ceti Debris Disk
A. Roberge, I. Kamp, B. Montesinos +12
We present far-IR/sub-mm imaging and spectroscopy of 49 Ceti, an unusual circumstellar disk around a nearby young A1V star. The system is famous for showing the dust properties of…
Multi-site campaign for transit timing variations of WASP-12 b: possible detection of a long-period signal of planetary origin
G. Maciejewski, D. Dimitrov, M. Seeliger +38
The transiting planet WASP-12 b was identified as a potential target for transit timing studies because a departure from a linear ephemeris was reported in the literature. Such dev…
The D/H ratio in the atmospheres of Uranus and Neptune from Herschel PACS observations
H. Feuchtgruber, E. Lellouch, G. Orton +9
Herschel-PACS measurements of the rotational R(0) and R(1) HD lines in the atmospheres of Uranus and Neptune are analyzed in order to derive a D/H ratio with improved precision for…
