New Methods for Determining the Ages of PMS Stars
Tim Naylor, N. J. Mayne, R. D. Jeffries +2
We present three new methods for determining the age of groups of pre-main-sequence stars. The first, creating empirical isochrones allows us to create a robust age ordering, but n…
ULTRACAM: an ultra-fast, triple-beam CCD camera for high-speed astrophysics
V. S. Dhillon, T. R. Marsh, M. J. Stevenson +15
ULTRACAM is a portable, high-speed imaging photometer designed to study faint astronomical objects at high temporal resolutions. ULTRACAM employs two dichroic beamsplitters and thr…
The Keele-Exeter young cluster survey: I. Low mass pre-main sequence stars in NGC 2169
R. D Jeffries, J. M. Oliveira, Tim Naylor +2
We have used R_C I_C CCD photometry from the Isaac Newton telescope and intermediate resolution spectroscopy from the Gemini North telescope to identify and characterise low-mass (…
SDSS J0926+3624, the first eclipsing AM CVn star, as seen by ULTRACAM
T. R. Marsh, V. S. Dhillon, S. Littlefair +6
We present light curves of SDSS J0926+3624, the first eclipsing AM CVn star, observed with the high-speed CCD camera ULTRACAM on the WHT. We find unusually that the accreting white…
