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…
Lightcurves for asteroids 18301 Konyukhov and 2022 West
Sinhué A. R. Haro-Corzo, Luis A. Villegas, Lorenzo Olguín +7
We report photometric analysis of two main-belt asteroids observed at the Observatorio Astronomico Nacional in the Sierra San Pedro Martir, Baja California, México. For 18301 Konyu…
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…
Multiple outflows in the planetary nebula NGC 6058
P. F. Guillén, R. Vázquez, L. F. Miranda +4
We present narrow-band [O III]lambda5007 and H-alpha images, as well as long-slit high-resolution echelle spectra of the planetary nebula NGC 6058. Our data reveal that NGC 6058 is…
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…
