RT Cru: spectra requested

Juan Luna (Universidad de Buenos Aires, Instituto de Astronomía y Física del Espacio) is drawing attention on the symbiotic star RT Cru


The symbiotic RT Cru has been getting some attention in the last years due to its high energy emission in X-rays. I have published a couple of papers about it:

http://adsabs.harvard.edu/abs/2018A%26A...616A..53L

http://adsabs.harvard.edu/abs/2007ApJ...671..741L

I would like to call the ARAS observers attention and encourage to follow spectroscopically this source. The AAVSO light curve is also showing an interesting behavior now, recovering from a faint state.



Here's the AAVSO lightcurve:
