Near-IR speckle imaging of massive young stellar objects
We present near-IR speckle images of 21 massive Young Stellar Objects(YSOs) associated with outflows. The aim of this study is to search forsub-arcsecond reflection nebulae associated with the outflow cavity. Wefind that 6 of the massive YSOs show a conical nebula which can beinterpreted in terms of reflected light from the dusty walls of theoutflow cavity. In all cases, the small scale structures seen in ourimages are compared with outflow indicators found in the literature. Noclear correlation is found between the presence of the reflectionnebulosity and any property such as degree of embeddedness. We also notethat 3 of the sources show close companions, one of them belonging alsoto the sample with conical nebula.Figures \ref{S140SpeckleFig}, \ref{S255SpeckleFig},\ref{Ha101Fig}-\ref{HGL490Fig} and\ref{GL2591SpeckleFig}-\ref{GL5180peckleFig} are only available inelectronic form at http://www.edpsciences.org

A spectrophotometric survey of stars along the Milky Way. IV
In the present paper a catalogue of spectrophotometric quantities,spectral types, monochromatic magnitudes and colour equivalents is givenfor all stars brighter than the magnitude m4400 = 10.5 in aregion of the Milky Way in Perseus. No absorption is found for starscloser than about r = 100 pc. The absorbing clouds are situated atdistances closer than 1 kpc and at about 2.5 kpc in the local arm andthe Perseus arm, respectively. The space between the two arms is freefrom absorption. It is also concluded that the Perseus arm continuesbeyond l = 140 deg, containing not only hydrogen gas but also dust to atleast l = 150 deg), while the content of OB stars decreases abruptly atl = 140 deg.
