Low CI/CO Abundance Ratio Revealed by HST UV Spectroscopy of CO-rich Debris Disks
Aoife Brennan, Luca Matrà, Sebastián Marino +6
The origin and evolution of CO gas in debris disks has been debated since its initial detection. The gas could have a primordial origin, as a remnant of the protoplanetary disk or…

Radio-continuum decrements associated to shadowing from the central warp in transition disc DoAr44
Carla Arce-Tord, Simon Casassus, William R. F. Dent +8
Warps have often been used to explain disc properties, but well characterised examples are important due to their role in disc evolution. Scattered light images of discs with centr…

Submillimetre dust polarisation and opacity in the HD163296 protoplanetary ring system
W. R. F. Dent, C. Pinte, P. C. Cortes +4
We present ALMA images of the sub-mm continuum polarisation and spectral index of the protoplanetary ringed disk HD163296. The polarisation fraction at 870μm is measured to be ~0.9…
