Chemical signatures of a warped protoplanetary disc
Alison K. Young, Richard Alexander, Catherine Walsh +3
Circumstellar discs may become warped or broken into distinct planes if there is a stellar or planetary companion with an orbit that is misaligned with respect to the disc. There i…
An upper limit for the growth of inner planets?
Andrew J. Winter, Richard Alexander
The exotic range of known planetary systems has provoked an equally exotic range of physical explanations for their diverse architectures. However, constraining formation processes…
Evidence for an MHD disk wind via optical forbidden line spectro-astrometry
E. T Whelan, I. Pascucci, U. Gorti +4
Spectro-astrometry is used to investigate the low velocity component (LVC) of the optical forbidden emission from the T Tauri stars RU Lupi and AS 205 N. Both stars also have high…
HD 143006: circumbinary planet or misaligned disc?
G. Ballabio, R. Nealon, R. D. Alexander +3
Misalignments within protoplanetary discs are now commonly observed, and features such as shadows in scattered light images indicate departure from a co-planar geometry. VLT/SPHERE…
