We present the discovery of two new hot Jupiters identified from the WASP survey, WASP-186b and WASP-187b (TOI-1494.01 and TOI-1493.01). Their planetary nature was established from SOPHIE spectroscopic observations, and additional photometry was obta...

Stars with accurate and precise effective temperature (Teff) measurements are needed to test stellar atmosphere models and calibrate empirical methods to determine Teff. There are few standard stars currently available to calibrate temperature indica... Read More about Fundamental effective temperature measurements for eclipsing binary stars I.

Very regular high-frequency pulsation modes in young intermediate-mass stars (2020)
Journal Article
Bedding, T. R., Murphy, S. J., Hey, D. R., Huber, D., Li, T., Smalley, B., …Vanderspek, R. K. (2020). Very regular high-frequency pulsation modes in young intermediate-mass stars. Nature, 581, 147 - 151. https://doi.org/10.1038/s41586-020-2226-8

Asteroseismology probes the internal structures of stars by using their natural pulsation frequencies1. It relies on identifying sequences of pulsation modes that can be compared with theoretical models, which has been done successfully for many clas...

We report the discovery of two transiting exoplanets from the WASP survey, WASP-150b and WASP-176b. WASP-150b is an eccentric (e = 0.38) hot Jupiter on a 5.6 day orbit around a V = 12.03, F8 main-sequence host. The host star has a mass and radius of...

If ? Dor-type pulsations are driven by the convective blocking mechanism, a convective envelope at a sufficient depth is essential. There are several hot ? Dor and hybrid star candidates in which there should not be an adequate convective envelope to... Read More about Spectroscopy of hot ?

Age dating of an early Milky Way merger via asteroseismology of the naked-eye star ν Indi (2020)
Journal Article

Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies. While these accreted stellar populations can be forensically identified as kinematically distinct structures within the Galaxy, it is difficult in general...
