J-PLUS: Identifying Outlier Spectral Energy Distributions in the Fourth Data Release Using Unsupervised Machine Learning
F. Quispe-Huaynasi, F. Roig, V. Loaiza-Tacuri +25
The selection of candidates belonging to rare or underrepresented stellar populations, as well as novel objects, is essential for spectroscopic follow-up. In this work, we demonstr…
The stellar occultation by (319) Leona on 13 September 2023 in preparation for the occultation of Betelgeuse
J. L. Ortiz, M. Kretlow, C. Schnabel +36
On 12 December 2023, the star Orionis (Betelgeuse) will be occulted by the asteroid (319) Leona. This represents an extraordinary and unique opportunity to analyze the diameter…
J-PLUS: Searching for very metal-poor star candidates using the SPEEM pipeline
Carlos Andrés Galarza, Simone Daflon, Vinicius M. Placco +25
We explore the stellar content of the Javalambre Photometric Local Universe Survey (J-PLUS) Data Release 2 and show its potential to identify low-metallicity stars using the Stella…
The VLT-FLAMES Tarantula Survey II: R139 revealed as a massive binary system
W. D. Taylor, C. J. Evans, H. Sana +22
We report the discovery that R139 in 30 Doradus is a massive spectroscopic binary system. Multi-epoch optical spectroscopy of R139 was obtained as part of the VLT-FLAMES Tarantula…
