HST SN 1987A Legacy

WPFC2 image from mid 1990's

20 years ago...

motion of Spot #1

Ring size:
1.6" East-West
1.2" North-South (but has ~45 dgree inclination)

The spot has moved 2 pixels or 0.050" in 7 years
or on a different set of images I get a motion for
spot #1 of 1.85 pixels @ 0.025 "/pixel = 0.046"

0.05"/1.6" = 0.03125 percent of the ring diameter

Time between the 1999 and 2006 image = 2785 days =2.4e8 seconds

Ring size=1.2e18cm diameter (from Nino's paper)
=1.2e13 km * 0.03125  =3.75e11 km

Velocity of 
=3.75e11 km / 2.4e8 seconds = 1562.5 km/sec

The Magellan echelle spectrum I took last
year @ H beta. There's emission of +/- 300 km/sec Full width @ zero or continuum
level. [OIII] +/- 200 km/sec... and lots of +/- 30 km/sec emission lines
from the stationary ring ??

from Peter Garnavich showing the ring brightness versus time . time runs up and angle left-right. Did the spots (2006 top of figure) show up in the bright regions (1994 bottom) of the ring ?? Are the Dark regions more dense then the brigher parts ???

resampled image of the mosaic with angle running along X and then each observation stacked on each other

Standard 3 color image

showing the nonspherical symmetry in the debris H alpha=Red F625W=Green F250W=Blue

F250W image

H alpha=Red [OIII]=Green F250W=Blue

HA/[OIII] 2003 = BLUE HA/[OIII] 2006 = RED If the ratio stays the same then we get white (or pink), because the left side is reddish, that means those spots have much more Ha flux to [OIII] then in 2003 /a>

[OIII]/[OIII] 2006 to 2003

next set of images from taken from ACS/HRC all with same scaling from Jan 2003 (year=15.8653)
--> Dec 2006 (year=19.7815)

I guess this is the image that I can make thats closest in color to
the previous HST release.

These are the Dec 2006 HRC observations.

SN 1987A Debris Light curves


WFPC and CTIO corrected mags...
The ground mags have the contribution of the ring in them. 
These mags have that contribution removed.
I normalized the stars (and therefore debris) mags to the CTIO mags. 
for stars.. this is probably okay. However, I didn't use any
corrections in going from HRC/F435W to B or WFPC2/F439W to B.
Corrections could be made for stars, but it doesn't make sences for
the debris (an emission line source).
