CVSO 30 is a young , active , weak-line T Tauri star ; it possibly hosts the only known planetary system with both a transiting hot-Jupiter and a cold-Jupiter candidate ( CVSO 30 b and CVSO 30 c ) .
We analyzed archival ROSAT , Chandra , and XMM- Newton data to study the coronal emission in the system .
According to our modeling , CVSO 30 shows a quiescent X-ray luminosity of \approx 8 \times 10 ^ { 29 } erg s ^ { -1 } .
The X-ray absorbing column is consistent with interstellar absorption .
XMM- Newton observed a flare , during which a transit of the candidate CVSO 30 b was expected , but no significant transit-induced variation in the X-ray flux is detectable .
While the hot-Jupiter candidate CVSO 30 b has continuously been undergoing mass loss powered by the high-energy irradiation , we conclude that its evaporation lifetime is considerably longer than the estimated stellar age of 2.6 Myr .
