Synthetic observations of protostellar multiple systems

O. Lomax, A. P. Whitworth

Observations of protostars are often compared with synthetic observations of models in order to infer the underlying physical properties of the protostars. The majority of these mo…

Characterizing accreting double white dwarf binaries with the Laser Interferometer Space Antenna and Gaia

Katelyn Breivik, Kyle Kremer, Michael Bueno +3

We demonstrate a method to fully characterize mass-transferring double white dwarf (DWD) systems with a helium-rich (He) WD donor based on the mass--radius relationship for He WDs.…

How do stars gain their mass? A JCMT/SCUBA-2 Transient Survey of Protostars in Nearby Star Forming Regions

Gregory J. Herczeg, Doug Johnstone, Steve Mairs +55

Most protostars have luminosities that are fainter than expected from steady accretion over the protostellar lifetime. The solution to this problem may lie in episodic mass accreti…

Very Deep Inside the SN 1987A Core Ejecta: Molecular Structures Seen in 3D

F. J. Abellán, R. Indebetouw, J. M. Marcaide +21

Most massive stars end their lives in core-collapse supernova explosions and enrich the interstellar medium with explosively nucleosynthesized elements. Following core collapse, th…

ALMA spectral survey of Supernova 1987A --- molecular inventory, chemistry, dynamics and explosive nucleosynthesis

M. Matsuura, R. Indebetouw, S. Woosley +26

We report the first molecular line survey of Supernova 1987A in the millimetre wavelength range. In the ALMA 210--300 and 340--360 GHz spectra, we detected cold (20--170 K) CO, 28S…

Uncrowding R 136 from VLT-SPHERE extreme adaptive optics

Z. Khorrami, F. Vakili, T. Lanz +12

This paper presents the sharpest near-IR images of the massive cluster R136 to date, based on the extreme adaptive optics of the SPHERE focal instrument implemented on the ESO/VLT…
