Non-azimuthal linear polarization in protoplanetary disks
H. Canovas, F. Ménard, J. de Boer +3
Several studies discussing imaging polarimetry observations of protoplanetary disks use the so-called radial Stokes parameters Q_phi and U_phi to discuss the results. This approach…
On the nature of the tertiary companion to FW Tau: ALMA CO observations and SED modeling
Claudio Caceres, Adam Hardy, Matthias R. Schreiber +7
It is thought that planetary mass companions may form through gravitational disk instabilities or core accretion. Identifying such objects in the process of formation would provide…
The inner environment of Z~CMa: High-Contrast Imaging Polarimetry with NaCo
H. Canovas, S. Perez, C. Dougados +7
Context. Z\,CMa is a binary composed of an embedded Herbig Be and an FU Ori class star separated by au. Observational evidence indicate a complex environment in which eac…
Probing the Final Stages of Protoplanetary Disk Evolution with ALMA
A. Hardy, C. Caceres, M. R. Schreiber +5
The evolution of a circumstellar disk from its gas-rich protoplanetary stage to its gas-poor debris stage is not understood well. It is apparent that disk clearing progresses from…
Gas inside the 97 au cavity around the transition disk Sz\,91
H. Canovas, M. R. Schreiber, C. Cáceres +9
We present ALMA (Cycle 0) band-6 and band-3 observations of the transition disk Sz\,91. The disk inclination and position angle are determined to be $i=49.5\degr\pm3.5\degr$ and $\…
The First Science Results from SPHERE: Disproving the Predicted Brown Dwarf around V471 Tau
A. Hardy, M. R. Schreiber, S. G. Parsons +10
Variations of eclipse arrival times have recently been detected in several post common envelope binaries consisting of a white dwarf and a main sequence companion star. The general…
Improving Signal to Noise in the Direct Imaging of Exoplanets and Circumstellar Disks
Zahed Wahhaj, Lucas A. Cieza, Dimitri Mawet +10
We present a new algorithm designed to improve the signal to noise ratio (SNR) of point and extended source detections in direct imaging data. The novel part of our method is that…
