The clumpy structure of ϵ Eridani's debris disc revisited by ALMA
ABSTRACT ϵ Eridani is the closest star to our Sun known to host a debris disc. Prior
observations in the (sub-) millimetre regime have potentially detected clumpy structure in the …

Coronal mass ejections and type II radio emission variability during a magnetic cycle on the solar-type star ϵ Eridani
We simulate possible stellar coronal mass ejection (CME) scenarios over the magnetic cycle
of epsilon Eridani (18 Eridani; HD 22049). We use three separate epochs from 2008, 2011 …
