Investigating the Rotational Phase of Stellar Flares on M dwarfs Using K2 Short Cadence Data
L. Doyle, G. Ramsay, J. G. Doyle +2
We present an analysis of K2 short cadence data of 34 M dwarfs which have spectral types in the range M0 - L1. Of these stars, 31 showed flares with a duration between 10-90…
A Comment on "A note on polarized light from Magnetars: QED effects and axion-like particles" by L.M. Capparelli, L. Maiani and A.D. Polosa
R. Turolla, S. Zane, R. Taverna +4
The recent detection of a large polarization degree in the optical emission of an isolated neutron star led to the suggestion that this has been the first evidence of vacuum polari…
The astrophysics of ultra-compact binaries
G. Nelemans, M. Wood, P. Groot +24
This white paper briefly describes the astrophysics of ultra-compact binaries, with emphasis of the challenges and opportunities in the next decade.
Recent observational progress in AM CVn binaries
G. Ramsay, C. Brocksopp, P. Groot +9
We present the results of some recent research on AM CVn systems. We present: X-ray/UV observations made using XMM-Newton; the X-ray grating spectrum of RX J1914+24; preliminary re…
A search for stellar X-ray sourcesin the Sagittarius and Carina dwarf galaxies - I: X-ray observations
G. Ramsay, K. Wu
ROSAT observations found no convincing evidence for X-ray sources located in local dwarf spheroidal galaxies (dSph). Now with more sensitive instruments on board Chandra and XMM-Ne…
The Seyfert-LINER Galaxy NGC 7213: An XMM-Newton Observation
R. L. C. Starling, M. J. Page, G. Branduardi-Raymont +3
We examine the XMM X-ray spectrum of the LINER-AGN NGC 7213, which is best fit with a power law, K-alpha emission lines from Fe I, Fe XXV and Fe XXVI and a soft X-ray collisionally…
