Neutral hydrogen related to Gould's belt

Journal Article:

Abstract

Lindblad (1967) has performed a Gaussian analysis of 21-cm line profiles, taking into account the direction of the galactic anticenter. One of the features considered had an unusually small velocity dispersion of 2.5 km/s and a very wide latitude distribution. Lindblad could explain the entire velocity curve with the aid of a single model. He suggested that this feature, called feature A, constitutes a local expanding cloud with an expansion age of some 60 million years. The present investigation is concerned with results regarding three regions. Region I contains the Lupus Loop SNR and parts of the Upper Centaurus-Lupus Association. The rest of this association, as well as parts of the Lower Centaurus-Crux Association, are within region II. Region III includes parts of the Upper Scorpius Association, as well as parts of S27, the remarkable H II region surrounding Zeta Oph. Gas motions were studied by conducting a Gaussian analysis of the H I profiles.
