RT Cru is a ZAND type variable star with orbital period of 325 days and pulsation period of 63 days. According to Enhanced LCG, last observation of RT Cru was made on 2022-08-31. In total, there are 33590 observations of this star in AAVSO database (29123 in V-band and 2893 in B-band). RT Cru's case was included and described in scientific publications. Here are few examples:
- "The Nature of the Hard X-Ray-Emitting Symbiotic Star RT Cru" - G. J. M. Luna ; J. L. Sokoloski,
- "Light curves of symbiotic stars in massive photomeric surveys II: S and D’-type systems" - M. Gromadzki ; J. Mikołajewska ; I. Soszyński,
- "Observations of suspected symbiotic stars" - D. Cieslinski ; F. Elizalde ; J. E. Steiner.
There have been 4 notices for RT Cru in the AAVSO Alert Notice over several years:
Therefore, I would like to provide continuity of photometric measurements. BSM-Berry (Bolt) is probably the best suited site for this proposal.
The star is said to be flickering in a 10-30 min. time scale.
All data would be submitted to AAVSO database after VPhot analysis.
