Journal Article
Maxted, Hellier, & Smalley. (2019). WASP-166b: a bloated super-Neptune transiting a V = 9 star. Monthly Notices of the Royal Astronomical Society, 3067 -3075. https://doi.org/10.1093/mnras/stz1903

We report the discovery of WASP-166b, a super-Neptune planet with a mass of 0.1 MJup (1.9 MNep) and a bloated radius of 0.63 RJup. It transits a V = 9.36, F9V star in a 5.44-d orbit that is aligned with the stellar rotation axis (sky-projected obliqu... Read More about WASP-166b: a bloated super-Neptune transiting a V = 9 star.

Physics Letters B, 798(10), Article 134894. https://doi.org/10.1016/j.physletb.2019.134894

During the slow neutron capture process in massive stars, reactions on light elements can both produce and absorb neutrons thereby influencing the final heavy element abundances. At low metallicities, the high neutron capture rate of 16O can inhibit...

3D Simulations and MLT. I. Renzini’s Critique (2019)
Journal Article
Arnett, W. D., Meakin, C., Hirschi, R., Cristini, A., Georgy, C., Campbell, S., Scott, L. J., Kaiser, E. A., Viallet, M., & Mocák, M. (2019). 3D Simulations and MLT. I. Renzini’s Critique. Astrophysical Journal, 882(1), 18. https://doi.org/10.3847/1538-4357/ab21d9

Renzini wrote an influential critique of “overshooting” in mixing-length theory (MLT), as used in stellar evolution codes, and concluded that three-dimensional fluid dynamical simulations were needed. Such simulations are now well tested. Implicit la... Read More about 3D Simulations and MLT. I. Renzini’s Critique.

Monthly Notices of the Royal Astronomical Society, 3200 -3217. https://doi.org/10.1093/mnras/stz2325

We present a method to map the total intrinsic reddening of a foreground extinguishing medium via the analysis of spectral energy distributions (SEDs) of background galaxies. In this pilot study, we implement this technique in two distinct regions of... Read More about The intrinsic reddening of the Magellanic Clouds as traced by background galaxies – I.

Social, Economic, and Political Contexts for Chemistry Through Sustainability. (2019)
Presentation / Conference Contribution
Haxton, K. (2019, August). Social, Economic, and Political Contexts for Chemistry Through Sustainability. Presented at Variety in Chemistry Education / Physics Higher Education Conference 2019, Schools of Physics and Chemistry at the University of Bristol

Chemistry has a complex relationship with society: on one hand income generator and employer, on the other polluter and exploiter. Chemistry students must, through their undergraduate degrees, learn to place their core chemical concepts in the wider...

Monthly Notices of the Royal Astronomical Society, 489(1), 1082 -1098. https://doi.org/10.1093/mnras/stz2158

The production of the neutron-capture isotopes beyond iron that we observe today in the Solar system is the result of the combined contribution of the r-process, the s-process, and possibly the i-process. Low-mass asymptotic giant branch (AGB) (1.5 &... Read More about NuGrid stellar data set – III.

Relative Importance of Convective Uncertainties (2019)
Presentation / Conference Contribution
Kaiser, E. A., Hirschi, R., Arnett, W. D., Cristini, A., Georgy, C., & Scott, L. J. A. (2018, June). Relative Importance of Convective Uncertainties. Presented at Nuclei in the Cosmos XV, Rome, Italy

Convection plays a key role in the evolution of stars due to energy transport and mixing of composition. Despite its importance, this process is still not well understood. One longstanding conundrum in all 1D stellar evolution codes is the treatment... Read More about Relative Importance of Convective Uncertainties.
