J-PLUS: Understanding outlier white dwarfs in the third data release via dimensionality reduction
C. López-Sanjuan, P. -E. Tremblay, A. del Pino +20
We present the white dwarf catalog derived from the third data release of the Javalambre Photometric Local Universe Survey (J-PLUS DR3), which covers 3284 deg2 using 12 optical fil…
J-VAR: Analysis of RR Lyrae light curves in seven optical bands
S. Kulkarni, H. Vázquez Ramió, C. López-Sanjuan +13
Context:RR Lyrae stars, with their accurate period and amplitude measurements, constrain stellar evolution and map Galactic structure. The Javalambre VARiability (J-VAR) survey is…
J-PLUS: The fraction of calcium white dwarfs along the cooling sequence
C. López-Sanjuan, P. -E. Tremblay, M. W. O'Brien +24
We used the Javalambre Photometric Local Universe Survey (J-PLUS) DR2 photometry in twelve optical bands over 2176 deg2 to estimate the fraction of white dwarfs with presence of Ca…
J-PLUS: Towards an homogeneous photometric calibration using Gaia BP/RP low-resolution spectra
C. López-Sanjuan, H. Vázquez Ramió, K. Xiao +21
We present the photometric calibration of the twelve optical passbands for the Javalambre Photometric Local Universe Survey (J-PLUS) third data release (DR3), comprising 1642 point…
J-PLUS: Discovery and characterisation of ultracool dwarfs using Virtual Observatory tools II. Second data release and machine learning methodology
P. Mas-Buitrago, E. Solano, A. González-Marcos +20
Ultracool dwarfs (UCDs) comprise the lowest mass members of the stellar population and brown dwarfs, from M7 V to cooler objects with L, T, and Y spectral types. Most of them have…
J-PLUS: Stellar Parameters, C, N, Mg, Ca and [α/Fe] Abundances for Two Million Stars from DR1
Lin Yang, Haibo Yuan, Maosheng Xiang +20
Context. The Javalambre Photometric Local Universe Survey (J-PLUS) has obtained precise photometry in twelve specially designed filters for large numbers of Galactic stars. Derivin…
J-PLUS: Spectral evolution of white dwarfs by PDF analysis
C. López-Sanjuan, P. -E. Tremblay, A. Ederoclite +17
We estimated the spectral evolution of white dwarfs with effective temperature using the Javalambre Photometric Local Universe Survey (J-PLUS) second data release (DR2), that provi…
