HD183648: a Kepler eclipsing binary with anomalous ellipsoidal variations and a pulsating component (2015)
Conference Proceeding
Derekas, A., Borkovits, T., Fuller, J., Szabó, G., Pavlovski, K., Csák, B., …Jankovics, I. (2015). HD183648: a Kepler eclipsing binary with anomalous ellipsoidal variations and a pulsating component. In EPJ Web of Conferences. https://doi.org/10.1051/epjconf/201510106021

IC 8560861 (HD 183648) is a marginally eccentric (e = 0.05) eclipsing binary with an orbital period of Porb = 31.973 d, exhibiting mmag amplitude pulsations on time scales of a few days. We present the results of the complex analysis of high and medi... Read More about HD183648: a Kepler eclipsing binary with anomalous ellipsoidal variations and a pulsating component.

Multiple star systems observed with CoRoT and Kepler (invited review) (2015)
Conference Proceeding
Southworth, J. (2015). Multiple star systems observed with CoRoT and Kepler (invited review). . https://doi.org/10.1051/epjconf/201510104001

The CoRoT and Kepler satellites were the first space platforms designed to perform high-precision photometry for a large number of stars. Multiple systems display a wide variety of photometric variability, making them natural benefactors of these mis...

Variable Emission from a Gaseous Disc around a Metal-Polluted White Dwarf (2015)
Conference Proceeding
Wilson, D. J., Gaensicke, B. T., Koester, D., Raddi, R., Breedt, E., Southworth, J., & Parsons, S. G. (2015). Variable Emission from a Gaseous Disc around a Metal-Polluted White Dwarf. In Vol. 493 – 19th European Workshop on White Dwarfs

We present the discovery of a variable gaseous disc around the metal-polluted DA white dwarf SDSS J1617+1620. Time-series spectroscopy obtained during the period 2006-2014 has shown the appearance of very strong double-peaked Ca ii 8600Å emission lin...

DEBCat: A Catalog of Detached Eclipsing Binary Stars (2015)
Conference Proceeding
Southworth, J. (2015). DEBCat: A Catalog of Detached Eclipsing Binary Stars. In Astronomical Society of the Pacific Conference Series

Detached eclipsing binary star systems are our primary source of measured physical properties of normal stars. I introduce DEBCat: a catalogue of detached eclipsing binaries with mass and radius measurements to the 2% precision necessary to put usefu...

Observational Studies of Transiting Extrasolar Planets (2014)
Conference Proceeding
Southworth, J. (2014). Observational Studies of Transiting Extrasolar Planets. In Living Together: planets, host stars and binaries (321 -336)

The study of transiting extrasolar planets is only 15 years old, but has matured into a rich area of research. I review the observational aspects of this work, concentrating on the discovery of transits, the characterization of planets from photometr...

HSTEP -- Homogeneous Studies of Transiting Extrasolar Planets (2012)
Conference Proceeding
Southworth, J. (2012). HSTEP -- Homogeneous Studies of Transiting Extrasolar Planets. . https://doi.org/10.1017/S174392131301332X

I give a summary of the HSTEP project: an effort to calculate the physical properties of the known transiting extrasolar planets using a homogeneous approach. I discuss the motivation for the project, list the 83 planets which have already been studi... Read More about HSTEP -- Homogeneous Studies of Transiting Extrasolar Planets.

Eclipsing Binary Stars: the Royal Road to Stellar Astrophysics (2012)
Conference Proceeding
Taylor. (2012). Eclipsing Binary Stars: the Royal Road to Stellar Astrophysics. In Proceedings of the workshop "Orbital Couples: Pas de Deux in the Solar System and the Milky Way" (51-58)

Russell (1948) famously described eclipses as the "royal road" to stellar astrophysics. From photometric and spectroscopic observations it is possible to measure the masses and radii (to 1% or better!), and thus surface gravities and mean densities,...

Homogeneous studies of transiting planets (2011)
Conference Proceeding
Southworth, J. (2011). Homogeneous studies of transiting planets. . https://doi.org/10.1017/S1743921311027177

The derived physical properties of the known transiting extrasolar planetary systems come from a variety of sources, and are calculated using a range of different methods so are not always directly comparable. I present a catalogue of the physical pr... Read More about Homogeneous studies of transiting planets.

Eclipsing binaries in open clusters (2003)
Conference Proceeding
Southworth, J., Maxted, P., & Smalley, B. (2003). Eclipsing binaries in open clusters.

Accurate physical parameters have been determined for two early-type detached eclipsing binaries in the open cluster h Persei (NGC 869). Masses accurate to 1.5% are derived from high-resolution spectroscopy and radii accurate to 4--6% have been obtai... Read More about Eclipsing binaries in open clusters.
