Inferring giant planets from ALMA millimeter continuum and line observations in (transition) disks
Stefano Facchini, Paola Pinilla, Ewine F. van Dishoeck +1
Potential signatures of proto-planets embedded in their natal protoplanetary disk are radial gaps or cavities in the continuum emission in the IR-mm wavelength range. ALMA observat…
Adapting astronomical source detection software to help detect animals in thermal images obtained by unmanned aerial systems
S. N. Longmore, R. P. Collins, S. Pfeifer +7
In this paper we describe an unmanned aerial system equipped with a thermal-infrared camera and software pipeline that we have developed to monitor animal populations for conservat…
Can dead zones create structures like a transition disk?
Paola Pinilla, Mario Flock, Maria de Juan Ovelar +1
[Abridged] Regions of low ionisation where the activity of the magneto-rotational instability is suppressed, the so-called dead zones, have been suggested to explain gaps and asymm…
Surprising detection of an equatorial dust lane on the AGB star IRC+10216
S. V. Jeffers, M. Min, L. B. F. M. Waters +6
Understanding the formation of planetary nebulae remains elusive because in the preceding asymtotic giant branch (AGB) phase these stars are heavily enshrouded in an optically thic…
Gas and dust structures in protoplanetary disks hosting multiple planets
P. Pinilla, M. de Juan Ovelar, S. Ataiee +4
Transition disks have dust-depleted inner regions and may represent an intermediate step of an on-going disk dispersal process, where planet formation is probably in progress. Rece…
Protoplanetary disc evolution affected by star-disc interactions in young stellar clusters
Giovanni P. Rosotti, James E. Dale, Maria de Juan Ovelar +4
Most stars form in a clustered environment. Therefore, it is important to assess how this environment influences the evolution of protoplanetary discs around young stars. In turn,…
Instrumental polarisation at the Nasmyth focus of the E-ELT
M. de Juan Ovelar, F. Snik, C. U. Keller +1
The ~39-m European Extremely Large Telescope (E-ELT) will be the largest telescope ever built. This makes it particularly suitable for sensitive polarimetric observations, as polar…
Imaging diagnostics for transitional discs
M. de Juan Ovelar, M. Min, C. Dominik +4
Transitional discs are a special type of protoplanetary discs where planet formation is thought to be taking place. These objects feature characteristic inner cavities and/or gaps…
The Extreme Polarimeter: Design, Performance, First Results & Upgrades
M. Rodenhuis, H. Canovas, S. V. Jeffers +4
Well over 700 exoplanets have been detected to date. Only a handful of these have been observed directly. Direct observation is extremely challenging due to the small separation an…
M&m's: An error budget and performance simulator code for polarimetric systems
Maria de Juan Ovelar, Frans Snik, Christoph U. Keller
Although different approaches to model a polarimeter's accuracy have been described before, a complete error budgeting tool for polarimetric systems has not been yet developed. Bas…
Direct imaging of a massive dust cloud around R Coronae Borealis
S. V. Jeffers, M. Min, L. B. F. M. Waters +5
We present recent polarimetric images of the highly variable star R CrB using ExPo and archival WFPC2 images from the HST. We observed R CrB during its current dramatic minimum whe…
