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…
CCD Photometry of Trapezia Stars I
A. Ruelas-Mayorga, L. J. Sánchez, A. Páez-Amador +2
We present photometric CCD observations of stars in four stellar trapezia ADS 15184, ADS 4728, ADS 2843, and ADS 16795. This study is performed on images obtained at the Observator…
CCD Photometry of the Globular Cluster NGC 5897
A. Ruelas-Mayorga, L. J. Sánchez, E. Macías-Estrada +1
We report CCD photometric observations of the globular cluster NGC 5897, in the Johnson system filters B, V , R, and I. With the values for these magnitudes we obtain various colou…
The interaction of the halo around the butterfly planetary nebula NGC650-1 with the interstellar medium
G. Ramos-Larios, M. A. Guerrero, A. Nigoche-Netro +7
With its bright and wide equatorial waist seen almost edge-on (the butterfly body) and the faint and broad bipolar extensions (the butterfly wings), NGC650-1 is the archetypical ex…
CCD photometry of the Globular Cluster NGC 6093
A. Ruelas-Mayorga, L. J. Sanchez, C. A. Bernal-Herrera +3
In this paper we present photometric CCD observations of the globular cluster NGC 6093 (M80) in filters B, V , R and I. We produce the colour-magnitude diagrams for this object and…
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…
