Continuous `stunted' outbursts detected from the Cataclysmic Variable KIC 9202990 using Kepler data
Gavin Ramsay, Pasi Hakala, Matt A Wood +4
Based on early Kepler data, Ostensen et al. (2010) found that KIC 9202990 showed a 4 hr and a two-week photometric period. They suggested the 4 hr period was a signature of an orbi…
Searching for I band variability in stars in the M/L spectral transition region
Gavin Ramsay, Pasi Hakala, J Gerry Doyle
We report on I band photometric observations of 21 stars with spectral types between M8 and L4 made using the Isaac Newton Telescope. The total amount of time for observations whic…
K2 and MAXI observations of Sco X-1 - Evidence for disc precession?
Pasi Hakala, Gavin Ramsay, Thomas Barclay +1
Sco X-1 is the archetypal low mass X-ray binary (LMXB) and the brightest persistent extra-solar X-ray source in the sky. It was included in the K2 Campaign 2 field and was observed…
Swift J0525.6+2416 and IGR J04571+4527: two new hard X-ray selected magnetic cataclysmic variables identified with XMM-Newton
F. Bernardini, D. de Martino, K. Mukai +4
IGR J04571+4527 and Swift J0525.6+2416 are two hard X-ray sources detected in the Swift/BAT and INTEGRAL/IBIS surveys. They were proposed to be magnetic cataclysmic variables of th…
The view from K2: Questioning the traditional view of flaring on early dM stars
Gavin Ramsay, J. Gerry Doyle
We use K2 short cadence data obtained over a duration of 50 days during Campaign 0 to observe two M1V dwarf stars, TYC 1330-879-1 and RXJ 0626+2349. We provide an overview of our d…
Dissecting accretion and outflows in accreting white dwarf binaries
D. de Martino, G. Sala, S. Balman +22
This is a White Paper in support of the mission concept of the Large Observatory for X-ray Timing (LOFT), proposed as a medium-sized ESA mission. We discuss the potential of LOFT f…
