A ring-like concentration of mm-sized particles in Sz 91
(Oxford Univ Press, 2016)
Models of planet formation and disc evolution predict a variety of observables in the dust structure of protoplanetary discs. Here, we present Atacama Large Millimeter/submillimeter Array (ALMA) Band-6 and Band-7 observations ...
HI bubbles surrounding southern optical ring nebulae: Anon(WR 23) and RCW 52
(EDP Sciences, 2005-12)
We analyze the interstellar medium in the environs of two hot and massive stars, HD 92809 (= WR 23, WC6) and LSS 1887 (O8V), which ionize the optical ring nebulae Anon(WR 23) and RCW 52, respectively. Our analysis is based ...
A branch-and-cut-and-price approach for the capacitated m-ring-star problem
(Elsevier Science BvAmsterdamHolanda, 2012)
Inhomogeneous molecular ring around the B[e] supergiant LHA 120-S 73.
(EDP Sciences, 2016-07)
Context. B[e] supergiants are evolved massive stars, enshrouded in a dense wind and surrounded by a molecular and dusty disk. Themechanisms that drive phases of enhanced mass loss and mass ejections, responsible for the ...
