Bl2—Lancaster Farming, Saturday, April 7,1984
Project winners at the annual
Delaware-County 4-H Spring Fair
held at the Granite Run Mall,
Media, have been announced by
Elmore R. Hunter, Urban 4-H
compared with the sun’s 8 billion to
10 billion years, says Stencel.
The fact that its’ relatively short
lived could mean that its com
panion has not yet formed, he
notes, or that it somehow is
preventing its companion from
forming.
At least 55 professional and
amateur astronomers in about a
dozen countries have telescopes
pointed toward Epsilon Aurieae to
try to detect its secret companion.
Besides groundbased instruments
taking photometric, spectroscopic,
polarimetric, and infrared
measurements, satellites also are
making ultraviolet and infrared
observations.
“It has to be protoplanetary
system. I don’t know how it could
be anything else,” says
astronomer James C. Kemp of the
University of Oregon, who
bases his statement on
preliminary results of his -■
monitoring of the polarized light.
Kemp and his assistants have
been watching Epsilon Aurigae
since late July 1982, through
telescopes at the Pine Mountain
Observatory, perched 6,300 feet up
in the mountains of Oregon’s
central desert region. His research
is supported in part by the National
Geographic Society.
“The pattern of polarized light
indicates that the eclipsing body is
a highly organized dense disk
strongly condensed and probably
rapidly spinning. Presumably
there is a star buried in the middle
that holds it together. Given what
we know of the formation of
planets, this disk seems to have the
right properties,” Kemp says. “It
may be in the process of con
densing, shrinking, and cooling
into cooler gaseous blobs that may
further condense into planets at

the same time becoming flatter

At this point, his studies indicate
that the disk is about 100 million
miles thick, with a billion-mile
diameter. However, preliminary
infrared measurements by Dana
E. Backman of the University of
Hawaii show the disk to be
somewhat thicker. Epsilon
Aungae’s mysterious companion
was first thought to be disk-shaped
and dense by astronomer Su-Shu
Huang of Northwestern University
in 1965.
It may be about a year after the
current eclipse ends before
scientists will be able to agree
about what they saw, Stencel says.
“It’s a matter of comparing
notes from all sources and trying
to decide what best explains the
data,” he says. The infrared
studies, which can probe regions
that appear transparent in or
dinary visible light, may hold the
key.
“With infrared we hope to see
through to what’s going on in the
center, whether there’s a hot
center, a cold center, or none at
all,” says Stencel.
An orbiting infrared telescope,
which last year provided the first
direct evidence of pther solar
systems, is expected to give clues
about Epsilon Aurigae when
further data are analyzed. The
Infrared Astronomy Satellite
found two potential planetary
systems around the stars Vega
and Fomalhaut.
Barring some astronomical
surprises, Stencel believes
scientists should be able to say the
same thing about Epsilon Aungae.
“I hope those studying the eclipse
of 2009 to 2011 will be affirming
what we have discovered,” he
says.
