On producers of cosmic organic compounds: exploring the boron abundance in lithium-rich K giant stars
N. A. Drake, R. de la Reza, V. V. Smith +1
The element boron belongs, together with lithium and beryllium, to a known trio of important elements for the study of evolutionary processes in low mass stars. Because B is the le…
Weak Magnetic Fields in Two Herbig Ae Systems: The SB2 AK Sco and the Presumed Binary HD 95881
S. P. Järvinen, T. A. Carroll, S. Hubrig +9
We report the detection of weak mean longitudinal magnetic fields in the Herbig Ae double-lined spectroscopic binary AK Sco and in the presumed spectroscopic Herbig Ae binary HD958…
Spectroscopic signatures of magnetospheric accretion in Herbig Ae/Be stars. I. The case of HD101412
M. Schöller, M. A. Pogodin, J. A. Cahuasqui +10
Models of magnetically-driven accretion and outflows reproduce many observational properties of T Tauri stars. This concept is not well established for the more massive Herbig Ae/B…
HARPS spectropolarimetry of three sharp-lined Herbig Ae stars: New insights
S. P. Järvinen, T. A. Carroll, S. Hubrig +5
Several arguments have been presented that favour a scenario in which the low detection rate of magnetic fields in Herbig Ae stars can be explained by the weakness of these fields…
