On the accretion process in a high-mass star forming region - A multitransitional THz Herschel-HIFI study of ammonia toward G34.26+0.15
M. Hajigholi, C. M. Persson, E. S. Wirström +8
[Abridged] Our aim is to explore the gas dynamics and the accretion process in the early phase of high-mass star formation. The inward motion of molecular gas in the massive star f…

How dusty is alpha Centauri? Excess or non-excess over the infrared photospheres of main-sequence stars
J. Wiegert, R. Liseau, P. Thébault +19
[Abridged] Debris discs around main-sequence stars indicate the presence of larger rocky bodies. The components of the nearby binary aCentauri have higher than solar metallicities,…
