The potassium absorption on HD189733b and HD209458b
Engin Keles, Matthias Mallonn, Carolina von Essen +9
In this work, we investigate the potassium excess absorption around 7699A of the exoplanets HD189733b and HD209458b. For this purpose, we used high spectral resolution transit obse…
New evidence for weak magnetic fields in Herbig Ae/Be stars
S. P. Järvinen, T. A. Carroll, S. Hubrig +2
In recent years Herbig Ae/Be stars receive considerable attention as their disks are believed to be the sites of on-going planet formation. Confirming the presence of magnetic fiel…
Magnetic activity of the young solar analogue V1358 Ori
L. Kriskovics, Zs. Kővári, K. Vida +3
Young, fast rotating single stars can show dramatically different magnetic signatures and levels of magnetic activity as compared with the Sun. While losing angular momentum due to…
The two magnetic components in the Herbig Ae SB2 system HD 104237
S. P. Järvinen, T. A. Carroll, S. Hubrig +4
We present longitudinal magnetic field measurements for the Herbig Ae primary and the T Tauri secondary in the SB2 system HD 104237. These measurements were c…
Warm and cool starspots with opposite polarities. A high-resolution Zeeman-Doppler-Imaging study of II Pegasi with PEPSI
K. G. Strassmeier, T. A. Carroll, I. V. Ilyin
We present a temperature and a magnetic-field surface map of the K2 subgiant of the active binary II Peg. Employed are high resolution Stokes IV spectra obtained with the new Potsd…
Surface magnetic activity of the fast-rotating G5-giant IN Comae, central star of the faint planetary nebula LoTr 5
Zs. Kővári, K. G. Strassmeier, K. Oláh +8
On the AGB, low to intermediate mass stars blow away their outer envelopes, forming planetary nebulae. Interaction between the planetary nebula and its central progenitor is poorly…
