Questions With Correct Answers || || || ||
How the transit detection method works.
|| || || || ||
Detects distant planets by measuring the minute
|| || || || || || ||
dimming of a star as an orbiting planet passes (transits)
|| || || || || || || || || ||
between it and the Earth || || || ||
The method the Kepler Spacecraft use to find exoplanets.
|| || || || || || || ||
Kepler used a photometer that continually monitored the
|| || || || || || || ||
brightness of ~150,000 stars in a fixed field of view
|| || || || || || || || ||
What the time between observed exoplanet transits
|| || || || || || ||
represents.
Time it takes to complete one orbit (orbital period)
|| || || || || || || ||
What a bigger drop in brightness means for an exoplanet
|| || || || || || || || || ||
transits.
Bigger drop in brightness means bigger planet (larger
|| || || || || || || ||
diameter)
,The types of planets the transit method detects most
|| || || || || || || || ||
easily.
Big planets close to their stars
|| || || || ||
How the radial velocity detection method works.
|| || || || || ||
Relies on the fact that the gravitational pull of an orbiting
|| || || || || || || || || || ||
planet will cause a star to wobble - move slightly toward
|| || || || || || || || || || ||
the Earth (blue Doppler shift) and then slightly away (red
|| || || || || || || || || ||
Doppler shift) each time the planet orbits || || || || || ||
What the Doppler Effect is.
|| || || ||
The apparent change in the frequency of a wave caused
|| || || || || || || || || ||
by relative motion between the source of the wave and
|| || || || || || || || || ||
the observer
||
What combining observations from the radial velocity and
|| || || || || || ||
transit method provides.
|| || ||
,The radial velocity detection method combined with
|| || || || || || ||
information from the transient method enables us to || || || || || || || ||
determine the mass of a planet || || || || ||
What we can estimate from knowing the mass and size of
|| || || || || || || || || || ||
an exoplanet.
||
Its density and its composition
|| || || ||
How the gravitational microlensing detection method
|| || || || || ||
works.
The same was as a magnifying lense; a closer star warps
|| || || || || || || || || || ||
space to bend the light of a more distant star and make it
|| || || || || || || || || || || || ||
look bigger ||
What the gravitational microlensing method detects
|| || || || || ||
better than other methods.
|| || ||
Planets around very distant stars
|| || || ||
How the direct imaging detection method works.
|| || || || || ||
, Blocks the overwhelming glare of stars to reveal the
|| || || || || || || || ||
reflected light of orbiting planets || || || ||
The types of planets the direct imaging method detects
|| || || || || || || || ||
better than other methods.
|| || ||
Planets far from their stars || || || ||
How we infer the chemistry of an exoplanet's
|| || || || || || || ||
atmosphere.
Passing light through a prism || || || ||
What the absorption spectrum of sunlight passing through
|| || || || || || ||
our atmosphere reveals.
|| || ||
Missing colors show up as black lines, indicating specific
|| || || || || || || || ||
gases are absorbing that part of the spectrum
|| || || || || || ||
How the TESS Space Telescope improves over the Kepler
|| || || || || || || || ||
Space Telescope. ||
