Meridional flow profile measurements with SOHO/MDI
U. Mitra-Kraev, M. J. Thompson
We present meridional flow measurements of the Sun using a novel helioseismic approach for analyzing SOHO/MDI data in order to push the current limits in radial depth. Analyzing th…
Properties of high-degree oscillation modes of the Sun observed with Hinode/SOT
U. Mitra-Kraev, A. G. Kosovichev, T. Sekii
Aims. With the Solar Optical Telescope on Hinode, we investigate the basic properties of high-degree solar oscillations observed at two levels in the solar atmosphere, in the G-ban…
The first observed stellar X-ray flare oscillation: Constraints on the flare loop length and the magnetic field
U. Mitra-Kraev, L. K. Harra, D. R. Williams +1
We present the first X-ray observation of an oscillation during a stellar flare. The flare occurred on the active M-type dwarf AT Mic and was observed with XMM-Newton. The soft X-r…
Loop length and magnetic field estimates from oscillations detected during an X-ray flare on AT Mic
U. Mitra-Kraev, L. K. Harra
We analyse oscillations observed in the X-ray light curve of the late-type star AT Mic. The oscillations occurred during flare maximum. We interpret these oscillations as density p…
Relationship between X-ray and ultraviolet emission of flares from dMe stars observed by XMM-Newton
U. Mitra-Kraev, L. K. Harra, M. Guedel +6
We present simultaneous ultraviolet and X-ray observations of the dMe-type flaring stars AT Mic, AU Mic, EV Lac, UV Cet and YZ CMi obtained with the XMM-Newton observatory. During…
Some Like it Hot: The X-Ray Emission of The Giant Star YY Mensae
Marc Audard, Alessandra Telleschi, Manuel Guedel +3
(Abridged abstract) We present an analysis of the X-ray emission of the rapidly rotating giant star YY Mensae observed by Chandra HETGS and XMM-Newton. Although no obvious flare wa…
