Astronomers spy possible baby planet in stellar womb
An image from the NACO system on ESO's Very Large Telescope shows a candidate protoplanet in the disc of gas and dust around the young star HD100546 in this picture released on March 2, 2013.Full Story

The bit missing is the mass of the parent star.
One other item which would be good in comparison/contrasts would be a log distance plot of the planets from the central star and a note on the planet mass.
Do this with the solar system and all the planets line up spaced out like pearls on a string. Apparently this alignment with tidal resonances is not an accident, & is a relic of the formation of the solar system.
This same effect may show up with other exoplanetary systems. Those found & plotted so far however appear in large part to show a much wider spacing than that of the solar system, and the planets in the system also appear to have a much larger difference in mass. The solar system by comparison appears to have a double gas giant system with Saturn @ 0.3 Jupiter masses being much bigger & closer than the average seen so far,(with a 1 and 0.07 mass being more typical; with as a result of mass similarities between Jupiter and Saturn, the tidal resonances doubled in the same space, with more planets in the system as a result.
Have a nice day: Ag
