Asymmetric Planetary Nebulae (APN) are formed by bipolar outflows through various mechanism like fast rotation (Blackman et al. 2001), magnetic field (Regos & Tout 1995) or binarity (Harpaz & Soker 1994; Soker 1996; Livio & Soker 2002). The binary scenario seems currently to be best supported by observations as the most efficient in producing the

It is found that the planetary nebula M1-32, which has a [WC4-5] core, shows a peculiar kinematics with bipolar outflows reaching ±200 km/s, while the main body is expanding radially with velocity of 15 km/s (Akras & Lopez 2012 , MNRAS, 425,2197; Rechy-García etal in preparation). Medina et al. (2006, RMAA, 42, 53 74) found high velocity wings in

We present internal proper motion measurements of more than five hundred positions of NGC 2392, based on images acquired with the WFPC2 on bord of the Hubble Space Telescope for two epochs separated by 8.805 yr. We measured the amount of motion of local structures in the nebula determining their relative shift during that interval. We compared two

The horizontal-branch (HB) morphology of globular clusters (GCs) is mainly determined by metallicity. However, the fact that GCs with almost the same metallicity exhibit different HB morphologies demonstrates that at least one more parameter is needed to explain the HB morphology. It has been suggested that one of these should be a global parameter

Context. To calibrate automatic pipelines that determine atmospheric parameters of stars, one needs a sample of stars, or "benchmark stars", with well-defined parameters to be used as a reference. Aims: We provide detailed documentation of the iron abundance determination of the 34 FGK-type benchmark stars that are selected to be the pillars for

Following a vast search for extended Planetary Nebulae (PNe) in the Galactic Plane using IPHAS, we present the first release of the "IPHAS Catalogue of Extended Nebulae". The catalogue in its current version contains more than one hundred spectroscopically identified PNe distributed from the Galactic Center to the Galactic Anticenter. These new
