Searching for Corannulene with ALMA: Observations of the Red Rectangle Nebula
Elise Koo, Alessandra Candian, Michiel Hogerheijde +6
Polycyclic Aromatic Hydrocarbons (PAHs) are organic molecules responsible for the Aromatic Infrared Bands (AIBs), observed across a multitude of astrophysical environments. Despite…
Re-analysis of the 267-GHz ALMA observations of Venus: No statistically significant detection of phosphine
I. A. G. Snellen, L. Guzman-Ramirez, M. R. Hogerheijde +2
Context: ALMA observations of Venus at 267 GHz have been presented in the literature that show the apparent presence of phosphine (PH3) in its atmosphere. Phosphine has currently n…
Compact planetary nebulae: Improved IR diagnostic criteria based on classification tree modelling
Stavros Akras, Lizette Guzman-Ramirez, Denise R. Gonçalves
Planetary nebulae (PNe) are strong H line-emitters and a lot of new PNe discoveries have been made by the SuperCOSMOS AAO/UKST H Survey (SHS) and the Isaac Newton Telescope P…
A census of symbiotic stars in the 2MASS, WISE and Gaia surveys
Stavros Akras, Lizette Guzman-Ramirez, Marcelo L. Leal-Ferreira +1
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…
Resolved imaging of the AR Puppis circumbinary disk
S. Ertel, D. Kamath, M. Hillen +14
Circumbinary disks are common around post-asymptotic giant branch (post-AGB) stars with a stellar companion on orbital time scales of a few 100 to few 1000 days. The presence of a…
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…
