ALMA observations of the circumstellar envelope around EP Aqr
P. T. Nhung, D. T. Hoai, P. Tuan-Anh +6
Atacama Large Millimetre/sub-millimetre Array (ALMA) observations of the CO(1-0) and CO(2-1) emissions from the circumstellar envelope of the Asymptotic Giant Branch (AGB) star EP…
Core fragmentation and Toomre stability analysis of W3(H2O): A case study of the IRAM NOEMA large program CORE
A. Ahmadi, H. Beuther, J. C. Mottram +30
The fragmentation mode of high-mass molecular clumps and the properties of the central rotating structures surrounding the most luminous objects have yet to be comprehensively char…
Astronomical detection of a radioactive molecule 26AlF in a remnant of an ancient explosion
Tomasz Kamiński, Romuald Tylenda, Karl M. Menten +6
Decades ago, -ray observatories identified diffuse Galactic emission at 1.809 MeV originating from decays of an isotope of aluminium, Al, that has a mean-life time…
De-projection of radio observations of axi-symmetric expanding circumstellar envelopes
P. T. Nhung, D. T. Hoai, P. Tuan-Anh +5
The problem of de-projection of radio line observations of axi-symmetric expanding circumstellar envelopes is studied with the aim of easing their analysis in terms of physics mode…
Fragmentation and disk formation during high-mass star formation: The IRAM NOEMA (Northern Extended Millimeter Array) large program CORE
H. Beuther, J. C. Mottram, A. Ahmadi +30
Aims: We aim to understand the fragmentation as well as the disk formation, outflow generation and chemical processes during high-mass star formation on spatial scales of individua…
