Fig. 7.


Optical and X-ray images centered on the eight new λ Cas analogs and the λ Cas candidate. All images are centered on the targets, 52 x 52 in size, and oriented with north up and east to the left. The X-ray images correspond to the 0.5-10.0 keV energy band (after merging all EPIC data when XMM-Newton is used), while the optical images are from the DSS survey (POSS2/UKSTU Red). For HD 316568, the Chandra data with ObsID 4547 and the XMM-Newton daa with ObsID 0402280101 are both shown; for HD 42054 the XMM-Newton dataset is shown rather than the zeroth-order Chandra data; for CQ Cir V771 Sgr, and V2156 Cyg images merging all Swift data were created with the online tool (see footnote 7 and Sect. 4.1.2).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
