Cracking open the "dragon egg": ALMA 1.3mm observations of a compact, young high-mass core candidate at 30mas resolution

A. T. Barnes, J. D. Henshaw, Á. Sánchez-Monge +14

Massive prestellar cores are a central assumption of core-accretion models of high-mass star formation, yet convincing observational examples remain rare. The "dragon egg" (C2c1a)…

A dependence of binary and planetary system destruction on subtle variations in the substructure in young star-forming regions

Richard J. Parker

Simulations of the effects of stellar fly-bys on planetary systems in star-forming regions show a strong dependence on subtle variations in the initial spatial and kinematic substr…

Photoevaporation versus enrichment in the cradle of the Sun

Miti Patel, Cheyenne K. M. Polius, Matthew Ridsdill-Smith +2

The presence of short-lived radioisotopes (SLRs) 26-Al and 60-Fe in the Solar system places constraints on the initial conditions of our planetary system. Most theories posit that…

On the origin of planetary-mass objects in NGC1333

Richard J. Parker, Catarina Alves de Oliveira

The dominant formation mechanism of brown dwarfs and planetary mass objects in star-forming regions is presently uncertain. Do they form like stars, via the collapse and fragmentat…

Isotopic enrichment of planetary systems from Asymptotic Giant Branch stars

Richard J. Parker, Christina Schoettler

Short-lived radioisotopes, in particular 26-Al and 60-Fe, are thought to contribute to the internal heating of the Earth, but are significantly more abundant in the Solar System co…

Mother of Dragons: A Massive, quiescent core in the dragon cloud (IRDC G028.37+00.07)

A. T. Barnes, J. Liu, Q. Zhang +15

Context: Core accretion models of massive star formation require the existence of massive, starless cores within molecular clouds. Yet, only a small number of candidates for such t…
