Most neutron capture elements have a double production by r- and s-processes, but the question of production sites is complex and still open. Recent studies show that including stellar rotation can have a deep impact on nucleosynthesis. We studied th...

The Magellanic Clouds are nearby dwarf irregular galaxies whose morphologies show different properties when traced by different stellar populations, making them an important laboratory for studying galaxy morphologies. We study the morphology of the... Read More about The VMC Survey - XXXIV. Morphology of Stellar Populations in the Magellanic Clouds.

Phenotypic Plasticity of Nest-Mate Recognition Cues in Formica exsecta Ants. (2019)
Journal Article

It is well established that many ant species have evolved qualitatively distinct species-specific chemical profile that are stable over large geographical distances. Within these species profiles quantitative variations in the chemical profile allows... Read More about Phenotypic Plasticity of Nest-Mate Recognition Cues in Formica exsecta Ants..

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.

A direct measurement of the 17O(a,?)21Ne reaction in inverse kinematics and its impact on heavy element production (2019)

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

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.
