Abstract
We present Gaia Early Data Release 3 (Gaia EDR3) high accurate astrometric and photometric data
and also Catalina Sky Survey (CSS ) phase-dependent light curves for three Young Stellar Objects (YSO).
They are LRL 245, 2MASS J04300424+3533238, and CVSO 592. These tree YSOs are presented as periodic variables in the Catalina Surveys Data Release-1 (CSDR1) data base.
CSS phase-dependent curve of LRL 245 shows periodicity with period P=234.66 days and amplitude
∆m≈4.0 mag. For this object high-resolution spectra in H-band (from 1.51 to 1.69 µm) was obtained by
the APOGEE instrument. LAMOST telescope moderate-resolution CCD spectra is available for object
2MASS J04300424+3522238 only. The spectra shows clear features of M dwarfs.
