Target Info
Target Name: EK DRA
Target No.: 5246
Category: STARS/CATACLYSMIC VARIABLES/OTHER GALACTIC SOURCES
Coordinates[J2000]: (219.75100, 64.29170)
Exp (ks): 9
Extended: N
Extent Size:
Background Restriction: N
Remarks:
Constraint Details
Monitor: Y
Criteria: We will monitor the star during March 13-24 as a part of the coordinated observations with H-alpha observations with SEIMEI telescope in Japan and TESS (sectors 49 and 50). This will provide an opportunity to search for superflares and filament eruption driven CMEs similar to the one detected with SEIMEI by the member of our team (Namekata et al. 2021, Nat. Astr).
Phase Dependent: Y
Epoch: 2022-03-13 09:59:59 UTC
Period: 2.76000000
Min: 0.0000
Max: 0.5000
Remarks: The rotationally modulated X-ray signal will be characterized with TESS observations of starspots.
Specific Time: Y
Start: 2022-03-13 09:59 UTC
End: 2022-03-24 09:50 UTC
Remarks: This time period between March 13-24, 2022 is selected to coordinate with the approved TESS and SEIMEI observations.
ToO: Y
Coordinate Observation: Y
Observatory: SEIMEI AND TESS OBSERVATORIES
Description: We will monitor the stellar flares in X-rays in coordination with the optical broad-band (TESS) and H-alpha spectroscopic observations with SEIMEI. We will also coordinate this with NuSTAR to search for hard X-ray emission found in a couple of superflares from Young Stellar Objects.
