Identification of planetary and proto-planetary nebulae candidates through akari infrared photometry
R. A. Marquez-Lugo, S. N. Kemp, G. Ramos-Larios +3
We utilized photometric data from the space telescope AKARI to identify potential planetary nebulae (PNe) and proto-planetary nebulae (PPNe) candidates. Using the colour-colour dia…
Spitzer mid-infrared spectroscopic observations of planetary nebulae
Héctor Mata, Gerardo Ramos-Larios, Martin A. Guerrero +7
We present Spitzer Space Telescope archival mid-infrared (mid-IR) spectroscopy of a sample of eleven planetary nebulae (PNe). The observations, acquired with the Spitzer Infrared S…
Blue luminous stars in nearby galaxies - UIT005: a possible link to the luminous blue variable stage
M. A. Urbaneja, A. Herrero, D. J. Lennon +2
(abridged) A detailed study of the blue supergiant UIT005 (B2-2.5Ia+) in M33 is presented. The results of our quantitative spectral analysis indicate that the star is a very lumino…
In savvy pursuit of Local Group blue massive stars
Miriam Garcia, Artemio Herrero, Norberto Castro +1
The important role of metallicity on massive star evolution and the combination of multi-object spectrographs and 10m class telescopes, have lead to numerous systematic studies of…
The Young Stellar Population of IC1613. I. A New Catalogue of OB Associations
M. Garcia, A. Herrero, B. Vicente +5
Context: Determining the parameters of massive stars is crucial to understand many processes in galaxies and the Universe, since these objects are important sources of ionization,…
