The orbit and nature of the semi-detached stellar companion of Sgr A* super-massive blackhole
Elia Leibowitz
In three previous papers I showed that the series of the midpoints of the times of all the X-ray flares of Sgr A* that have been detected so far harbor a statistical trend termed p…
Possible evidence from the flaring activity of Sgr A* for a star at a distance of ~3.3 Schwarzscild radii from the blackhole
Elia Leibowitz
The frequent flaring events in the X-ray and the NIR radiation of Sgr A* seem not to be periodic in time. However, statistical regularities, here termed "modulations by a pacemaker…
A 149 minute periodicity underlies the X-ray flaring of Sgr A*
Elia Leibowitz
In a recent paper (Leibowitz 2017) I have shown that the 39 large X-ray flares of Sgr A* that were recorded by Chandra observatory in the year 2012, are concentrated preferably aro…
A Pacemaker with P=2.48 hour Modulated the Generator of Flares in the X-ray Light Curve of Sgr A* in the year 2012
Elia M. Leibowitz
In an intensive observational campaign in the 9 month duration of Chandra X-ray Visionary Project that was conducted in the year 2012, 39 large X-ray flares of Sgr A* were recorded…
Periods in a 87 Years Light Curve of the Symbiotic Star MWC 560
Elia M. Leibowitz, Liliana Formiggini
We have constructed a visual light curve of the symbiotic star MWC covering the last 87 years of its history. The data were assembled from the literature and from the AAVSO data ba…
The peculiar light curve of the Symbiotic Star AX Per of the last 125 years
Elia M. Leibowitz, Liliana Formiggini
We analyze the last 125 years optical light curve of the symbiotic star AX Per through some remarkable correlations that we discovered in its power spectrum. The data were assemble…
