Activity on a Li-rich giant: DI Psc revisited
Levente Kriskovics, Zsolt Kővári, Krisztián Vida +1
We present a new Doppler imaging study for the Li-rich single K-giant DI Psc. Surface temperature maps are reconstructed for two subsequent rotation cycles. From the time evolution…
Surface differential rotation of IL Hya from time-series Doppler images
Zsolt Kővári, Levente Kriskovics, Katalin Oláh +4
We present a time-series Doppler imaging study of the K-subgiant component in the RS CVn-type binary system IL Hya (P orb=12.905 d). From re-processing the unique long-term spectro…
On the reliability of measuring differential rotation of spotted stars
Zsolt Kővári, János Bartus, Levente Kriskovics +2
Cross-correlation of consecutive Doppler images is one of the most common techniques used to detect surface differential rotation (hereafter DR) on spotted stars. The disadvantage…
Doppler imaging of stellar surface structure - XXIV. The lithium-rich single K-giants DP Canum Venaticorum and DI Piscium
Zs. Kovari, H. Korhonen, K. G. Strassmeier +3
We present the first Doppler imaging study of the two rapidly rotating, single K-giants DP CVn and DI Psc in order to study the surface spot configuration and to pinpoint their ste…
