Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): V721 CrA and BN CrA have wide and structured disks in polarised IR

Gabriele Columba, Elisabetta Rigliaco, Raffaele Gratton +8

We present near-infrared scattered-light observations of the disks around two stars of the Corona Australis star-forming region, V721 CrA, and BN CrA, obtained with VLT/SPHERE, in…

SPHERE RefPlanets: Search for epsilon Eridani b and warm dust

C. Tschudi, H. M. Schmid, M. Nowak +35

We carried out very deep VLT/SPHERE imaging polarimetry of the nearby system Eps Eri based on 38.5 hours of integration time with a 600 - 900 nm broadband filter to search for pola…

Polarization aberrations in next-generation giant segmented mirror telescopes (GSMTs) I. Effect on the coronagraphic performance

Ramya M. Anche, Jaren N. Ashcraft, Sebastiaan Y. Haffert +8

Next-generation large segmented mirror telescopes are expected to perform direct imaging and characterization of Earth-like rocky planets, which requires contrast limits of $10^{-7…

A multiwavelength analysis of the spiral arms in the protoplanetary disk around WaOph 6

S. B. Brown-Sevilla, M. Keppler, M. Barraza-Alfaro +23

[Full abstract in the paper] In recent years, protoplanetary disks with spiral structures have been detected in scattered light, millimeter continuum, and CO gas emission. The mech…

Characterizing the morphology of the debris disk around the low-mass star GSC~07396-00759

C. Adam, J. Olofsson, R. G. van Holstein +17

Context. Debris disks have commonly been studied around intermediate-mass stars. Their intense radiation fields are believed to efficiently remove the small dust grains that are co…

A survey of the linear polarization of directly imaged exoplanets and brown dwarf companions with SPHERE-IRDIS. First polarimetric detections revealing disks around DH Tau B and GSC 6214-210 B

R. G. van Holstein, T. Stolker, R. Jensen-Clem +22

Young giant planets and brown dwarf companions emit near-infrared radiation that can be linearly polarized up to several percent. This polarization can reveal the presence of a cir…
