Discovery of WASP-174b: Doppler tomography of a near-grazing transit (2018)
Journal Article
Maxted, Hellier, & Smalley. (2018). Discovery of WASP-174b: Doppler tomography of a near-grazing transit. Monthly Notices of the Royal Astronomical Society, 5307-5313. https://doi.org/10.1093/mnras/sty2197

We report the discovery and tomographic detection of WASP-174b, a planet with a near-grazing transit on a 4.23-d orbit around a V = 11.9, F6V star with [Fe/H] = 0.09 ± 0.09. The planet is in a moderately misaligned orbit with a sky-projected spin–orb... Read More about Discovery of WASP-174b: Doppler tomography of a near-grazing transit.

WASP-147b, 160Bb, 164b, and 165b: two hot Saturns and two Jupiters, including two planets with metal-rich hosts (2018)
Journal Article
Lendl, M., Anderson, D. R., Bonfanti, A., Bouchy, F., Burdanov, A., Collier Cameron, A., …West, R. G. (2019). WASP-147b, 160Bb, 164b, and 165b: two hot Saturns and two Jupiters, including two planets with metal-rich hosts. Monthly Notices of the Royal Astronomical Society, 482(1), 301 -312. https://doi.org/10.1093/mnras/sty2667

We report the discovery of four transiting hot Jupiters, WASP-147, WASP-160B, WASP-164, and WASP-165 from the WASP survey. WASP-147b is a near Saturn-mass (MP = 0.28MJ) object with a radius of 1.11RJ orbiting a G4 star with a period of 4.6 d. WASP-16...

WASP-128b: a transiting brown dwarf in the dynamical-tide regime (2018)
Journal Article
Hodzic, V., Triaud, A. H. M. J., Anderson, D. R., Bouchy, F., Cameron, A. C., Delrez, L., …West, R. (2018). WASP-128b: a transiting brown dwarf in the dynamical-tide regime. Monthly Notices of the Royal Astronomical Society, 481(4), 5091-5097. https://doi.org/10.1093/mnras/sty2512

Massive companions in close orbits around G dwarfs are thought to undergo rapid orbital decay due to runaway tidal dissipation. We report here the discovery of WASP-128b, a brown dwarf discovered by the WASP survey transiting a G0V host on a 2.2 d or...

A chemical survey of exoplanets with ARIEL (2018)
Journal Article
Maxted. (2018). A chemical survey of exoplanets with ARIEL. Experimental Astronomy, 135 - 209. https://doi.org/10.1007/s10686-018-9598-x

Thousands of exoplanets have now been discovered with a huge range of masses, sizes and orbits: from rocky Earth-like planets to large gas giants grazing the surface of their host star. However, the essential nature of these exoplanets remains largel... Read More about A chemical survey of exoplanets with ARIEL.

Comparison of the power-2 limb-darkening law from the Stagger-grid to Kepler light curves of transiting exoplanets (2018)
Journal Article
Maxted. (2018). Comparison of the power-2 limb-darkening law from the Stagger-grid to Kepler light curves of transiting exoplanets. Astronomy & Astrophysics, A39 -?. https://doi.org/10.1051/0004-6361/201832944

Inaccurate limb-darkening models can be a significant source of error in the analysis of the light curves for transiting exoplanet and eclipsing binary star systems, particularly for high-precision light curves at optical wavelengths. The power-2 lim... Read More about Comparison of the power-2 limb-darkening law from the Stagger-grid to Kepler light curves of transiting exoplanets.

Discovery and characterisation of long-period eclipsing binary stars from Kepler K2 campaigns 1, 2 and 3 (2018)
Journal Article
Maxted. (2018). Discovery and characterisation of long-period eclipsing binary stars from Kepler K2 campaigns 1, 2 and 3. Astronomy & Astrophysics, A38 -?. https://doi.org/10.1051/0004-6361/201732463

The Kepler K2 mission now makes it possible to find and study a wider variety of eclipsing binary stars than has been possible to-date, particularly long-period systems with narrow eclipses. Our aim is to characterise eclipsing binary stars observed... Read More about Discovery and characterisation of long-period eclipsing binary stars from Kepler K2 campaigns 1, 2 and 3.

The Exoplanet Climate Infrared TElescope (EXCITE) (2018)
Journal Article
Maxted. (2018). The Exoplanet Climate Infrared TElescope (EXCITE). Proceedings of SPIE, https://doi.org/10.1117/12.2314225

Although there are a large number of known exoplanets, there is little data on their global atmospheric properties. Phase-resolved spectroscopy of transiting planets – continuous spectroscopic observation of planets during their full orbits – probes...

WASP 0639-32: a new F-type subgiant/K-type main-sequence detached eclipsing binary from the WASP project (2018)
Journal Article
Hellier, & Maxted. (2018). WASP 0639-32: a new F-type subgiant/K-type main-sequence detached eclipsing binary from the WASP project. Astronomy & Astrophysics, A135 - A135. https://doi.org/10.1051/0004-6361/201731435

Aims. Our aim is to measure the masses and radii of the stars in a newly-discovered detached eclipsing binary system to a high precision (˜1%), enabling the system to be used for the calibration of free parameters in stellar evolutionary models.

Absolute parameters for the F-type eclipsing binary BW Aquarii (2018)
Journal Article
Maxted. (2018). Absolute parameters for the F-type eclipsing binary BW Aquarii. Research Notes of the American Astronomical Society, 2(2), https://doi.org/10.3847/2515-5172/aac720

BW Aqr is a bright eclipsing binary star containing a pair of F7V stars. The absolute parameters of this binary (masses, radii, etc.) are known to good precision so they are often used to test stellar models, particularly in studies of convective ove...
