We report the discovery of a third planet transiting the star TOI-1260, previously known to host two transiting sub-Neptune planets with orbital periods of 3.127 and 7.493 d, respectively. The nature of the third transiting planet with a 16.6-d orbit... Read More about Discovery of TOI-1260d and the characterization of the multiplanet system.

A CHEOPS-enhanced view of the HD 3167 system (2022)
Journal Article
Maxted. (2022). A CHEOPS-enhanced view of the HD 3167 system. Astronomy & Astrophysics, https://doi.org/10.1051/0004-6361/202243778

Much remains to be understood about the nature of exoplanets smaller than Neptune, most of which have been discovered in compact multi-planet systems. With its inner ultra-short period planet b aligned with the star and two larger outer planets d-c o... Read More about A CHEOPS-enhanced view of the HD 3167 system.

Effect of trivalent rare earth doping in cadmium silicates hosts: a theoretical study (2022)

Neutron crystallography reveals mechanisms used by Pseudomonas aeruginosa for host-cell binding (2022)
Journal Article
(2022). Neutron crystallography reveals mechanisms used by Pseudomonas aeruginosa for host-cell binding. Nature communications, https://doi.org/10.1038/s41467-021-27871-8

Pseudomonas aeruginosa employs lectins to bind to its host cells, and is known to be the major cause of lung infections. Lectin B (LecB) from Pseudomonas aeruginosa binds specifically to galactose and fucose and is important for pathogenicity, adhesi...

Context. The HD 108236 system was first announced with the detection of four small planets based on TESS data. Shortly after, the transit of an additional planet with a period of 29.54 d was serendipitously detected by CHEOPS. In this way, HD 108236...

Estimating the Convective Turnover Time (2022)
Journal Article
Wright. (2022). Estimating the Convective Turnover Time. Astrophysical Journal, 1-6. https://doi.org/10.3847/1538-4357/ac9cd8

The introduction of the Rossby number (R0), which incorporates the convective turnover time (t), in 1984 was a pioneering idea for understanding the correlation between stellar rotation and activity. The convective turnover time, which cannot be meas... Read More about Estimating the Convective Turnover Time.

The VLT-FLAMES Tarantula Survey Observational evidence for two distinct populations of massive runaway stars in 30 Doradus (2022)
Journal Article
Observational evidence for two distinct populations of massive runaway stars in 30 Doradus. Astronomy & Astrophysics, https://doi.org/10.1051/0004-6361/202244677

Context. The origin of massive runaway stars is an important unsolved problem in astrophysics. Two main scenarios have been proposed, namely: dynamical ejection or release from a binary at the first core collapse. However, their relative contribution...
