Oscillation frequencies and mode lifetimes in alpha Centauri A
Timothy R. Bedding, Hans Kjeldsen, R. Paul Butler +5
We analyse our recently-published velocity measurements of alpha Cen A (Butler et al. 2004). After adjusting the weights on a night-by-night basis in order to optimize the window f…

RVTESS I: Modeling Asteroseismic Signals with Simultaneous Photometry and RVs
Jiaxin Tang, Sharon X. Wang, Yaguang Li +22
Detecting small planets via the radial velocity method remains challenged by signals induced by stellar variability, versus the effects of the planet(s). Here, we explore using Gau…

Spectroscopic Characterization of LOFAR Radio-emitting M dwarfs
E. Koo, G. Stefansson, R. D. Kavanagh +20
Recent observations with the LOw Frequency ARray (LOFAR) have revealed 19 nearby M dwarfs showing bright circularly polarised radio emission. One of the possible sources of such em…
