The corona of GJ 1151 in the context of star-planet interaction
G. Foster, K. Poppenhaeger, J. D. Alvarado-Gómez +1
The low-mass star GJ 1151 has been reported to display variable low-frequency radio emission, which has been interpreted as a signpost of coronal star-planet interactions with an u…
A Study of RR1 Lightcurve Modulation in OGLE_III Bulge Time-series
Douglas L. Welch, Grant Foster
We report the results of our study of lightcurve modulation in a sample of 493 RR1 variables from the OGLE-III survey of galactic bulge fields. Each object in this list has 1500 or…
A Search for SS Cyg Outburst Predictors
A. Price, A. A. Henden, G. Foster +20
We report null results on a two year photometric search for outburst predictors in SS Cyg. Observations in Johnson V and Cousins I were obtained almost daily for multiple hours per…
The Variability of R,N,C Stars from HIPPARCOS and AAVSO Data
M. Grenon, J. A. Mattei, L. Eyer +1
Accurate photometry was obtained for all programme stars during the 3.3-year HIPPARCOS mission. The final observing programme included several hundred Mirae (M), semiregular (SR) l…
Mode switching in the nearby Mira-like variable R Doradus
T. R. Bedding, A. A. Zijlstra, A. Jones +1
We discuss visual observations spanning nearly 70 years of the nearby semiregular variable R Doradus. Using wavelet analysis, we show that the star switches back and forth between…
