The VMC Survey -- XL. Three-dimensional structure of the Small Magellanic Cloud as derived from red clump stars

B. L. Tatton, J. Th. van Loon, M. -R. L. Cioni +12

Galaxy interactions distort the distribution of baryonic matter and can affect star formation. The nearby Magellanic Clouds are a prime example of an ongoing galaxy interaction pro…

Double trouble: Gaia reveals (proto)-planetary systems that may experience more than one dense star-forming environment

Christina Schoettler, Richard J. Parker

Planetary systems appear to form contemporaneously around young stars within young star-forming regions. Within these environments, the chances of survival, as well as the long-ter…

Testing and Validating Two Morphological Flare Predictors by Logistic Regression Machine Learning

M. B. Korsos, R. Erdelyi, J. Liu +1

Whilst the most dynamic solar active regions (ARs) are known to flare frequently, predicting the occurrence of individual flares and their magnitude, is very much a developing fiel…

Planet formation in intermediate-separation binary systems

O. Panić, T. J. Haworth, M. G. Petr-Gotzens +13

We report the first characterisation of the individual discs in the intermediate separation binary systems KK Oph and HD 144668 at millimetre wavelengths. In both systems the circu…

A dearth of young and bright massive stars in the Small Magellanic Cloud

A. Schootemeijer, N. Langer, D. Lennon +7

Massive star evolution at low metallicity is closely connected to many fields in high-redshift astrophysics, but poorly understood. The Small Magellanic Cloud (SMC) is a unique lab…
