Confirmation and characterization of Galactic planetary nebulae: insights from a spectroscopic study
D. A. Beleño-Molina, L. Olguín, L. F. Miranda +2
We present a spectroscopic investigation of 25 objects previously reported as possible Planetary Nebulae (PNe) in recent catalogs to obtain their physical properties and to establi…
A spectroscopic census in young stellar regions: the Sigma Orionis cluster
Jesús Hernández, Nuria Calvet, Alice Perez +7
We present a spectroscopic survey of the stellar population of the Sigma Orionis cluster. We have obtained spectral types for 340 stars. Spectroscopic data for spectral typing come…
Submillimeter polarisation and magnetic field properties in the envelopes of proto-planetary nebulae CRL 618 and OH 231.8+4.2
L. Sabin, Q. Zhang, A. A. Zijlstra +5
We have carried out continuum and line polarisation observations of two Proto-planetary nebulae (PPNe), CRL 618 and OH 231.8+4.2, using the Submillimeter Array (SMA) in its compact…
New Galactic supernova remnants discovered with IPHAS
L. Sabin, Q. A. Parker, M. E. Contreras +7
As part of a systematic search programme of a 10-degree wide strip of the Northern Galactic plane we present preliminary evidence for the discovery of four (and possibly five) new…
Observational Study of the Multistructured Planetary Nebula NGC 7354
M. E. Contreras, R. Vázquez, L. F. Miranda +3
We present an observational study of the planetary nebula (PN) NGC 7354 consisting of narrowband Halpha and [NII]6584 imaging as well as low- and high-dispersion long-slit spectros…
