Characterisation of the Planetary Nebula Tc 1 Based on VLT X-Shooter Observations
Isabel Aleman, Marcelo L. Leal-Ferreira, Jan Cami +11
We present a detailed analysis of deep VLT/X-Shooter observations of the planetary nebula Tc 1. We calculate gas temperature, density, extinction, and abundances for several specie…

We present a new census of Galactic and extragalactic symbiotic stars (SySts). This compilation contains 323 known and 87 candidate SySts. Of the confirmed SySts, 257 are Galactic…
A machine learning approach for identification and classification of symbiotic stars using 2MASS and WISE
Stavros Akras, Marcelo L. Leal-Ferreira, Lizette Guzman-Ramirez +1
In this second paper in a series of papers based on the most-up-to-date catalogue of symbiotic stars (SySts), we present a new approach for identifying and distinguishing SySts fro…
