hello everyone
my name is Neil Hepburn and this is the astronomy research project
blue supergiant star born in the wild
our first slide
we have images of the blue supergiant star in April 2013
Doctor Youichi Ohyama and Dr. Ananda Hota
discovered a blue supergiant star
located far beyond our Milky Way galaxy in the constellation Virgo
the constellation virgo located in the
upper right corner and the images shown
represent how large the blue supergiant is compared to our own
sun and if you see
the blue supergiant is much larger than the Sun
over 55 million years ago
the blue supergiant star emerged in a chaotic environment Starmer Schmidt long
trail of gas
removed from the Galaxy IC 3418
as it spread rapidly into the Virgo cluster
and interacted with hot plasma of the surrounding Intra Cluster medium
below
actually have a picture up the blue supergiant
in a spectroscopic context
now we have instruments that were used
instruments used were the Subaru telescope
the Canada France Hawaii telescope and nasa's Galaxy Evolution Explorer (Galex)
also known as the GALEX with these instruments it was possible to view the
Stars formation
in a spectroscopic context now
onto the capabilities of the telescope the Galex
Is an orbiting space UV telescope
It can see light wavelengths from 135 Nanometers to 280 NM
the Canada France Hawaii Telescope
is a prime focus Cassegrain configuration
with the usable a aperture diameter 3.58
and Subaru telescope is reflecting Cassegrain telescope
diameter 8.3 meters this provides
a wider field view of view
and noting that the Canada France Hawaii Telescope and Subaru telescope
are both located in Mauna Kea Hawaii
on to other recent discoveries through this type of research
astronomers found an odd looking spiral galaxy
shown in the upper left hand corner this image that plows through the cluster
after being accelerated to at least 3.5 million kilometres
to the our by the enormous combined gravity the clusters dark matter
hot gas and hundreds Galaxy as
speeds through at rams into the hot gas that permeates the cluster
its gas in Stars is pulled away by the gravitational tidal forces
exerted by the cluster just as the forces exerted by our moon
and Sun pull the earths oceans
now we have other events....*
the blue supergiant star
is quite possibly the farthest star in a spectroscopic observation
in the future with the construction of the 30
meter telescope there's more potential for stellar spectroscopy
as you can see these are all pictures of what the future
thirty meter telescope will look like and
through better technology more
observations will be possible and last but not least
here's a HR diagram to the right and through this study
was very interesting to see other material pertains we have studied in
class
it will be interesting what stars astronomers will find in the future
new technology and current research the limits
are infinite and here's our quiz
number one the HR diagram
what spectral class so blue supergiant star
number two and what constellation did the blue supergiant form ?
for 3 what of observation is this study ?
at this time
I'd like to thank you all for listening to my presentation
and I hope you're informed of
the new blue supergiant star
thank you
