DOI: 10.1051/0004-6361/201832930
Abstract: Context. Little is known about how high-mass stars form. Around 30% of the young high-mass stars in the Galaxy are observed at the edges of ionized (H ii) regions. Therefore these are places of choice… read more here.

DOI: 10.1088/1538-3873/ac4c9c
Abstract: We review the use of young low mass stars and protostars, or young stellar objects (YSOs), as tracers of star formation. Observations of molecular clouds at visible, infrared, radio and X-ray wavelengths can identify and… read more here.

DOI: 10.1093/mnras/staa1656
Abstract: The mass growth of protostars is a central element to the determination of fundamental stellar population properties such as the initial mass function. Constraining the accretion history of individual protostars is therefore an important aspect… read more here.

DOI: 10.1093/mnras/staa176
Abstract: The evolution of low-mass stars into red giants is still poorly understood. During this evolution the core of the star contracts and, simultaneously, the envelope expands -- a process known as the `mirror'. Additionally, there… read more here.

DOI: 10.1093/mnras/staa187
Abstract: We investigate how a protoplanetary disc's susceptibility to gravitational instabilities and fragmentation depends on the mass of its host star. We use 1D disc models in conjunction with 3D SPH simulations to determine the critical… read more here.

DOI: 10.1093/mnras/staa883
Abstract: We use a suite of SPH simulations to investigate the susceptibility of protoplanetary discs to the effects of self-gravity as a function of star-disc properties. We also include passive irradiation from the host star using… read more here.
