Four new PLanetesimals Around TYpical and Pre-main seqUence Stars (PLATYPUS) Debris Discs at 8.8mm

Brodie J. Norfolk, Sarah T. Maddison, Jonathan P. Marshall +9

Millimetre continuum observations of debris discs can provide insights into the physical and dynamical properties of the unseen planetesimals that these discs host. The material pr…

ALMA and VLA Observations of EX Lupi in its Quiescent State

Jacob Aaron White, Á. Kóspál, A. G. Hughes +15

Extreme outbursts in young stars may be a common stage of pre-main-sequence stellar evolution. These outbursts, caused by enhanced accretion and accompanied by increased luminosity…

New millimeter CO observations of the gas-rich debris disks 49 Cet and HD 32297

Attila Moór, Quentin Kral, Péter Ábrahám +7

Previous observations revealed the existence of CO gas at nearly protoplanetary level in several dust-rich debris disks around young A-type stars. Here we used the ALMA 7m-array to…

A multi-wavelength study of the debris disc around 49 Cet

Nicole Pawellek, Attila Moór, Julien Milli +17

In a multi-wavelength study of thermal emission and scattered light images we analyse the dust properties and structure of the debris disc around the A1-type main sequence star 49~…

The surprisingly low carbon mass in the debris disk around HD 32297

Gianni Cataldi, Yanqin Wu, Alexis Brandeker +18

Gas has been detected in a number of debris disks. It is likely secondary, i.e. produced by colliding solids. Here, we report ALMA Band 8 observations of neutral carbon in the CO-r…

Science with an ngVLA: Resolving the Radio Complexity of EXor and FUor-type Systems with the ngVLA

Jacob Aaron White, Marc Audard, Péter Ábrahám +17

Episodic accretion may be a common occurrence in the evolution of young pre-main sequence stars and has important implications for our understanding of star and planet formation. M…
