Comparison of Gaia BP/RP spectra with LDS (Low Dispersion Spectroscopy) photographic sky surveys

Hudec, R.

Blue (BP) and Red (RP) Photometer low-resolution spectral data is one of the exciting new products in the third data release of ESA satellite Gaia (Gaia DR3) https://gaia.aip.de/cms/services/spectra-access/. The Gaia "photometric mode" RP/BP generates ultra-low-dispersion prism spectra of celestial sources. The LDS (Low-Dispersion Spectroscopy) as…

Long term follow-up coverage of Gaia photometric alert sources by Ondrejov robotic telescopes

Jelínek, M.; Štrobl, J.; Hudec, R.

The robotic telescopes at the Ondrejov Observatory are providing long-term optical multi-color coverage for selected 25 Gaia alert triggers located in the northern sky hemisphere. I will present and briefly discuss examples of selected results, mostly unpublished, obtained with these devices. In addition to that, I will present and discuss the pot…
