Analysis of Binary O-type Star Systems Using Recurrent Neural Networks
Miguel Flores R., Luis J. Corral, Celia R. Fierro-Santillán +1
This work presents an initial analysis of the estimation of effective temperature and surface gravity for simulated O-type binary systems using a recurrent neural network. The prop…
Disentangling stellar atmospheric parameters in astronomical spectra using Generative Adversarial Neural Networks
Minia Manteiga, Raúl Santoveña, Marco A. Álvarez +4
A method based on Generative Adversaria! Networks (GANs) is developed for disentangling the physical (effective temperature and gravity) and chemical (metallicity, overabundance of…
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…
O-type Stars Stellar Parameter Estimation Using Recurrent Neural Networks
Miguel Flores R., Luis J. Corral, Celia R. Fierro-Santillán +1
In this paper, we present a deep learning system approach to estimating luminosity, effective temperature, and surface gravity of O-type stars using the optical region of the stell…
Stellar Spectra Models Classification and Parameter Estimation Using Machine Learning Algorithms
Miguel Flores R., Luis J. Corral, Celia R. Fierro-Santillán
The growth of sky surveys and the large amount of stellar spectra in the current databases, has generated the necessity of developing new methods to estimate atmospheric parameters…
Dark matter inside early-type galaxies as function of mass and redshift
A. Nigoche-Netro, G. Ramos-Larios, P. Lagos +6
We study the behaviour of the dynamical and stellar mass inside the effective radius (re) of early-type galaxies (ETGs). We use several samples of ETGs -ranging from 19 000 to 98 0…
The tidal filament of NGC 4660
S. N. Kemp, C. Martinez-Robles, R. A. Marquez-Lugo +6
NGC 4660, in the Virgo cluster, is a well-studied elliptical galaxy which has a strong disk component (D/T about 0.2-0.3). The central regions including the disk component have ste…
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,…
An Analysis of STIS HST UV Spectra of M33 early B Supergiants
M. A. Urbaneja, A. Herrero, R. P. Kudritzki +3
We present terminal velocities of M33 B-supergiants, obtained from STIS HST spectra as part of our programme to investigate the Wind Momentum -- Luminosity Relationship (WLR) in th…
