Timescale-dependent X-ray to UV time lags of NGC 4593 using high-intensity XMM-Newton observations with Swift and AstroSat
Max W. J. Beard, Ian M. McHardy, Kavita Kumari +6
We present a 140ks observation of NGC 4593 with XMM-Newton providing simultaneous and continuous PN X-ray and OM UV (UVW1 2910Å) lightcurves which sample short-timescale variations…
X-ray Activity Variations and Coronal Abundances of the Star-Planet Interaction candidate HD 179949
Anshuman Acharya, Vinay L. Kashyap, Steven H. Saar +2
We carry out detailed spectral and timing analyses of the X-ray data of HD 179949, a prototypical example of a star with a close-in giant planet with possible star-planet…
Deepest far ultraviolet view of a central field in the Coma cluster by AstroSat UVIT
Smriti Mahajan, Kulinder Pal Singh, Joseph E. Postma +3
We present analysis of the far ultraviolet (FUV) emission of sources in the central region of the Coma cluster (z=0.023) using the data taken by the UVIT aboard the multi-wavelengt…
The AstroSat Observatory
