MAXI and NICER observations of a long flare from UX Ari
Abstract
MAXI detected a large X-ray flare from the RS CVn-type star UX Ari at 2018-11-24 15:54 UT. The flare peak occurred near 2018-11-25, and the peak spectrum is well reproduced by a distribution of thermal emission with a maximum temperature kT > 3.5 keV. The estimated flux in the 2-10 keV band is 1.1 +/- 0.3 x 10-9 erg/s/cm2.
