Goals
• To measure properties of star clusters using
CCD imaging and Spectroscopy using the DSS7 spectroscope
• To learn more about analytical techniques
such as photometry and spectroscopy

The Solar System
<http://www.kiroastro.com/images/perspective/earth2.jpg>.
•
Average Sun- provides energy (Hamilton,1995)
•
•
•
Eight Planets
Revolve around the Sun
Other satellites such as comets and meteors

Galaxies
• Our solar system is part of the Milky Way
Galaxy
• Whole solar system orbits the center of
the Milky Way
• Galaxy is one in billions (Hamilton,2009)
Open Clusters
•
•
•
•
Younger stars
Held together by gravity (Batinelli,1991)
All same age, composition
Tell us about early stellar
evolution(Archinal, 2003)

Globular Clusters
• Inside all galaxies are Globular Clusters (Kulesa,2009).
• Dense bunches of thousands of stars
• All extremely old, same stage in formation same
composition, no active star formation(Hester, 2006).
• Teach us about later stellar evolution (Taplur,1997)

Stellar Evolution
HR Diagram
• Graphical
interface
between
observation
and stellar
evolution.
(Thompson,
1997)
• Based on
observations
, other facts
can be
derived.
•<http://www.bramboroson.com/astro/images/hrdiagram.jpg>.
Spectroscopy
• Used to study the physical properties of a star
such as surface temperature or color. (Kulesa,
2005).
• Most large telescopes have spectroscopes.
(Seeds, 2005)
• Now being used at amateur level.
•http://loke.as.arizona.edu/~ckulesa/camp/spectroscopy_intro.html>.

Photometry
• Measurement of Luminosity of an object.
(Martinez,1997
• Generally measured on a CCD imager.
• Long exposure time to get fuller image.
(Martinez,1997)

Active Galactic Nuclei
• Super massive black holes
• Center of Galaxy
• Emit Enormous amounts of energy
Literature Review
Gilliand (1991) used CCD
imaging techniques to
create light curves for
starts in M67; an open
cluster.
Literature Review
Van den Bherg did photometry and spectroscopy
of globular clusters.
Literature Review
Cowie ET AL,
performed
spectroscop
y of various
cluster stars.
Literature Review
Montgomery
ET AL did b-v
photometry of
open clusters.
