Subject: SN 1993J update
4-23-93
SN 1993J enthusiasts,
Here are a few notes, as well as Taichi Kato's photometry update.
Now that the supernova has a reasonably normal spectrum, with
well-developed P-Cygni line profiles, it is important to continue
spectroscopy over a wide wavelength range and photometry in as many
bands as possible (to get the bolometric light curve). We should be
able to get an excellent distance to SN 1993J using the Expanding
Photosphere Method, and this will be compared with other estimates
(Cepheids, etc.).
Potential contributors of spectra and photometry are reminded to
e-mail reduced data to me as soon as possible, preferably in 2-column
ASCII format.
Cheers,
Alex Filippenko

From Gerard de Vaucouleurs (gav@astro.as.utexas.edu)
If you can reach the Spanish observers, Messrs. F. Garcia, J. Ripero,
F. Pujol, and D. Rodriguez, could you please ask them to precisely
identify their comparison stars and adopted magnitudes for their
critically important early observations of SN1993J on March 28-31.
Likewise it would be important to obtain similar information from
Mr. A. Neely for his observations of March 28 and 29.
Please send any information you may be able to elicit to some of the
'nodes' in the SN1993J club [in particular, to Alex Filippenko]
for re-diffusion to all interested parties. Thank you for your help.

From Roberta Humphreys (roberta@aps1.spa.umn.edu) and Greg Aldering:
[Alex's editorial note: I think the evidence for a rather low reddening
to SN 1993J is quite strong (weakness of 2200 A feature, weakness of
interstellar lines, very blue color at maximum, shape of spectrum after
maximum, etc.). Thus, I personally think that Roberta's low-reddening
option 3 (see below) is more realistic than the high-reddening option,
regardless of the derived reddening to other stars within 20" of SN 1993J.]
Notes on Blended Image and Possible Composite Spectrum
Roberta Humphreys and Greg Aldering
The image of the probable progenitor is defintely blended and the
observed energy distribution must be a composite of two or more stars.
The measured magnitudes of the progenitor object now cover the
wavelength range from U to I and allow for the possibility of modeling
the energy distribution. The recently reported I magnitude by Blakeslee
and Tonry ( circ #5758) has been very important for tieing down the
contribution from a red component. ( They reported V=20.8 and I=19.4)
We have also measured UBV and R photographic magnitudes for several
stars within about 20 arcsec of the SN in an attempt to get a realistic
estimate of the reddening in that region. We have sufficient multi-
color data on 3 of these objects to estimate their reddening. These 3
are 10 to 15 arcsec from the SN. We find Av values of .8, 1.0 and 1.5 mag.
and adopt Av = 1 mag for fitting the observed energy distribution.
Adopted magnitudes for the energy distribution:
I= 19.4 , R= 20.0, V= 20.8, B= 21.8 , U= 21.7 mag.
We decided to use V= 20.8 because of the many measurements of the
progenitor at this brightness.
We calculated a grid of different fits to the observed energy
distribution for different combinations of supergiant spectral types
using published colors and used a chi-squared test to select the best
fits. A few acceptable fits included an O star or early B-type supergiant
but because of the lack of Halpha emission we decided to rule them out (
see Richmond circ. # 5739 ).
These fits are for two stars only. Of course more might be present.
1. For Av = 1.0 mag the range of acceptable combinations are:
a. G8 I + B5 I 33% at V ( percent contribution of hot component at V)
+ B8 I 37% "
+ A2 I 48% "
b. K2 I + B5 I 48% "
+ B8 I 53% "
+ A2 I 68% "
c. K3 I + B5 I 57% "
+ B8 I 63% "
+ A2 I 80% "
2. As an example adopt the K2 star, we then derive for a true distance
modulus of 27.6 mag:
Mv Mbol Mv Mbol
B5 -7.0 -7.8 + K2 -7.1 -7.7
B8 -7.1 -7.6 + K2 -7.0 -7.6
A2 -7.4 -7.6 + K2 -6.6 -7.2
Thus the red component ( which is probably most people's choice
for the SN ) is a 4500K star with a luminosity appropriate for a star
with an initial mass near 15 Msun.
3. If one wants a fit with no reddening, the results for the cool
component aren't much different with Mbol about -7.2 but the blue
component is much less luminous at Mbol of -5.5 mag.
Needed: a good, deep CCD V image obtained under good seeing prior
to outburst. We have good deep J and F plates under good seeing that
show an association of stars 1 - 2 or more magnitudes fainter than
the progenitor image within 10 arcsec. There are even a few faint
images on our U plate. However our V plate ( IIaD ) doesn't go as deep.
If we could get some V magnitudes for the same stars we would have the
potential of measuring a C-M diagram for the association which would
be very interesting.
Anyone interested in a collaboration please get in touch with us.

THE ASTRONOMER SEQUENCE FOR SN 1993J
There still appears to be uncertainty over the basis of the TA sequence
in some e-mail exchanges. Comparison stars and individual estimates were
included in my first database listing.
The Astronomer chart was first distributed as long ago as 1983 Apr 3 as
part of the UK Nova/Supernova Patrol.
A revised chart also plotting the supernova was distributed on
Early Warning Circular 133 on March 30, within hours of the discovery
announcement.
A graphical chart was also sent on TA Electronic Circular 722 on
1993 Apr 1 (21.25UT)
Although the Thompson/Bryan chart has some common sequence stars, it was
our aim to restrict the number of comparisons to those providing
sufficient reasonable 'steps' for a visual observer and minimising
work if a re-reduction was necessary.
If one of observers used a star not on our 'restricted list' below then
only its magnitude (without decimal point) appears in our listing under
'estimate'.
