Probing Flare-Associated Eruptions on AB Doradus via X-ray Absorption Variations

Shweta Didel, Jeewan C Pandey, Abhishekh K Srivastava

In this work, we investigate eruptive phenomena associated with X-ray flares on AB Doradus using observations from XMM-Newton. Our aim is to detect such events with the help of con…
