The detection of 1.809 MeV gamma-ray line emission from the Cygnus X complex by the COMPTEL telescope is one of the most convincing proves of massive star nucleosynthesis in our Galaxy. The Cygnus X complex is an extremely active nearby region, containing several star forming regions, OB associations and young open star clusters. It houses some of

We analyze the statistical properties of the circumnuclear H II regions of a sample of 52 nearby galaxies (v

The prime objectives of the workshop were to: inform the community about the science opportunities of the Solar Orbiter mission; to provide a forum for sharpening and focussing the science goals; allow the hardware groups and instrument proposers to critically review the payload; establish international contacts and collaborations.

The definition of a cost effective deployment mechanism to deploy 180° panel like appendages in a safe way and with minimum end stroke deployment shock has been a challenge that led the design to achieve a low cost, light, compact, simple, flexible, modular, and low power demanding configuration. This mechanism is composed of an active hinge, that

In a search for emission line objects made in a southern region of M 33 using narrow band filters centered on [O III], Hα and adjacent continua, we detect some known and new objects that can be classified as planetary nebulae candidates (PNc). This search, the deepest one made up to now in M 33, has allowed us to detect 48 PNc, from which 14 have a
