"saturday" came from
-Rotating neutron stars
-Strong Magnetic Fields
-They pulsate since the rotation axis does not align with the magnetic field axis (light
house effect) Lecture 17, Slide 23
-Energy from pulsars comes from rotational energy
-Receive photons in gamma-ray, X-ray, optical, and radio bands
-Pulsars are losing rotational energy to radiation
-Rotating slower => takes them more time to complete rotation
-SO period increases for a pulsar over time

Property of Star - Distance
distance = 1/parallax
nucleur fusion
combination of nuclei to produce heavier nuclei with the release of energy
supergiant star
a star of very high luminosity
Who measured the distance to the moon?
On what day does summer officially begin?
Summer solstice
Cepheid variable
Star whose luminosity varies in the characteristic way, with a rapid rise in brightness followed by a slower decline. The period of a Cepheid variable star is related to its luminosity, so a determination of this period can be used to obtain an estimate of the star's distance.
The method of spectroscopic parallax is used to find the ____ of a star through knowledge of its _____.
distance, spectral type
Inside the Roche Limit,
large moons are torn apart
waxing crescent
phase btw new moon and first quarter
Astronomers have not yet been able to detect planets outside our solar system
• Because gamma rays have very short wavelengths, gamma-ray telescopes can achieve extremely high angular resolution
pulsating variable star

normal galaxy
There are billions of galaxies in the observable universe. They have quite a variety of shapes and sizes. Normal galaxies emit most of their radiation as visible light. The Hubble classification scheme defines four basic categories of normal galaxies - spirals, barred spirals, ellipticals, and irregulars. This classification is based on appearance.
Into which category do the majority of stars fall?
main sequence
What is the chief component of the Venusian atmosphere?

Net Force
The total amount of push or pull (forces) from an exterior agent or source acting upon a mass.
Nuclear Fusion
the combination of the nuclei of small atoms to form a larger nucleus; releases energy
An event in which a planet passes in front of a star (or the Sun) as seen from Earth. Only Mercury and Venus can be seen in transit of our Sun. The search for transits of extrasolar planets is an important planet detection strategy.

Most asteroids are found in the asteroid belt, which lies between the orbits of:

to run slowly

What is that gas and dust called in star formation?
Interstellar medium
With respect to the horizon, on any one night, Mars appears to move
east to west always.
Spectral line
sharp dip or peak in a spectrum at a characteristic wavelength
The equation of all three statements of the universal law of gravitation
Fg = G((m1 x m2)/d^2)
Size of an electron orbit
larger it is, higher the energy, smallest possible orbit --> smallest possible energy

What do these dust bunnies accomplish?

manufactured in cores of very massive stars
The mare on Ganymede were formed by
water erupting and spreading over the surface

orbit faster than astronomers would expect based on the galactic mass we can see
4. Nineteen neutrinos were detected from a supernova in our neighboring galaxy, the
Large Magellanic Cloud, on January 1987 (SNa 1987A). What did we learn about the
supernova explosion from this observation?
(b) The star that exploded was a massive star and neutrinos were produced when
its iron core collapsed to a neutron star
The greenhouse effect on Venus does which of the following?
causes the surface to be much hotter than it would otherwise be
What is so unusual about Pluto's orbit?
It is the most inclined to the ecliptic of the 9 planets?
According to Newton's first law:
A body at rest, tends to stay at rest and a body in motion tends to stay in motion.
Uranus is similar to Neptune in that it has
1) about the same mass and radius.
2) about the same internal composition
3) about the same cloud surface temperature

The Local Group (5 million light years across)
Ch.19 Q#36: Where would be the most likely place to find an ionization nebula? (a) int the halo (b) in the bulge (c) in the spiral arm *explain your answer*
We would most likely find that in c the spiral arm as it should be where active star formation is
Ch.19 Q#31: How do we determine the Milky Way's mass outside the Sun's orbit? (a) from the Sun's orbital velocity and its distance from the center of our galaxy (b) from the orbits of halo stars near the Sun (c) from the orbits of stars and gas clouds orb
C because in the book it says we have to consider the suns orbit and of mass beyond its orbit. (not 100% sure on this but I think that's what the book says)
