Techniques of measurements

What is parallax?

D pc 

parcsec

Techniques of measurements

• Basics of Parallax :
• Arc (S ) = radii (r) x angle (p)
•
•
•
•

r
r
r
r

…{ angle is physically measured, Arc is dist
bet S & E, radii is dist bet Earth & star }
= S/p x 360/2 x pi (degrees) ... { 1 deg = 3600 sec}
= 206265 x S/p
… { p is in arcsec}
= 206265 AU / p (arcsec)
= 1 parsec = 206265 x 15,00,00,000 kms = r / 9.46 x 1012 Ly = 3.26 Ly

• Distance in parsec Dpc = 1/p (arc sec)
• 1pc = 3.26ly = 206265 A.U.

• For stars having co-latitude  :
Measured change = True change / cos 
β

•

Parallax method is reliable up to about 1kpc

Magnitude, Scales & Calculations

• Magnitude scale – Originally by Hipparchus :
– After the sunset the first set of stars to be seen were 1st magnitude
stars, then 2nd, 3rd, … magnitude stars are visible.
– Hence the brightest stars are 1st magnitude while the faintest stars are
6th magnitude stars.

• When quantitative studies was done with the visual
appearance and the amount of light received from the
stars it was observed that the magnitudes are
logarithmically related to the flux of light emitted by the
stars.



• The flux l is defined as the amount of energy received per
unit area per unit time. e.g. we receive solar flux of 1400 W/m2.
• The flux received is inversely proportional to the square of
the distance.
• If the two stars emit flux l1 and l2, then their magnitudes
m1 and m2 respectively are related by the formula:
m2 – m1 = - 2.5 log(l2/l1)
• The 6th magnitude star is 100 times fainter than the 1st
magnitude star.


What’s Ref :
• A survey of hundred 6th magnitude (visually the faintest) stars
around the pole star was done. The average flux of these 100
‘north polar sequence’ stars was taken as the flux for the 6th
magnitude star.
• From that, for m = 0, the flux is 2.48 x 10–8 W/m2
• Once the fixed point of magnitude scale was defined this way,
the brightest star have magnitude even negative. E.g. the
Sirius has magnitude of –1.47, Venus can have magnitude
of – 4.4


Magnitude scale :



Apparent/Visual and Absolute magnitudes
• In order to compare the real brightness of stars, one uses
absolute magnitude (M) - It is the apparent magnitude of an
object when it is placed at a distance of 10pc.

• The sun’s apparent magnitude is – 26.8, while its
absolute magnitude is 4.5
• A star might look brighter than another star
– Either, it is actually brighter
– Or, it is closer to us than the other star


Relation between m and M :
• M = m – 5 log Dpc + 5
• Canopus (the second brightest star in the
night sky) has apparent magnitude of -0.72,
while the absolute magnitude is -2.5
• Estimate its distance.

• Sirius has m = - 1.46 and M = 1.41
• Estimate the distance of Sirius.

Distance Estimation using HR diagram
• Knowing the spectral class of
stars one can determine its
absolute magnitude
• Knowing
the
apparent
magnitude we can determine
its distance
• All O class stars have same
brightness. Hence by finding
O type star in distant cluster –
one can determine cluster
distance

Sun – A perfectly black body!

Wien’s displacement Law

• maxT = 0.29 cm-K
• Larger the surface temperature, the star peaks at smaller wavelength

Colour Index
• Magnitude gives only information about the flux, while
the colour index gives information about the colour of
the star, which might be useful to know the structure of
the star/ its position in HR diagram.
• To find the colour index, typically three different filters
are used. U, B, V
• B: Blue filter has central wavelength of 440nm
• V: Visual filter has central wavelength of 568nm

• The apparent magnitudes using these filters are found.
• Then B-V colour index is calculated.
– For bluish star, magnitude using B filter is smaller than that
using V filter. Hence B-V number is negative.
– Similarly B-V number positive means the stars are reddish in
colour.
– E.g. Betelguese has colour index B–V = 1.50 while Rigel has
colour index = –0.03

Standard Candles :
• If we had standard light bulbs around the
universe, we could have found distance from
the source by measuring the intensity of light
from that source alone.
• Such sources are called “standard candles”.
• They are:
– Cepheid Variables
– Supernovae

Variable Stars
• Some stars are found to have variable magnitudes.
• Their magnitudes increase and decrease over the period.
• The first such star was observed in 1596 by Fabricius.
– It was o-Ceti or Mira.
– Its period is 11 months (332 days)
– Its magnitude varies between 3.5 to 9

• In 1784,  Cephei, a yellow supergiant star was found to
be variable : Its period is 5d 8h 37m

Cepheid Variables
• Stars having similar light
variation as  Cephei are
called Cepheid variables.
• Cepheid
variables
are
supergiant stars and can be
seen at distances out to about
10-20 Mpc.
 American astronomer
Henrietta Leavitt looked at
many Cepheid variables in
SMC.
 She found the period
luminosity relation (reported
in 1912).

• One needs a distance
measurement from some
other method for at least one
Cepheid – parallax for delta
Cephei or distance to SMC.

Period – Luminosity relation


Types of spectra

• Hot solid bodies show continuous spectra
• Atomic gases show line spectra

Supernovae
• Constant absolute magnitude of
-19.6
• Type I – no hydrogen line in
spectrum, shows Si emission
• From white dwarfs or stars
close to the Chandrasekhar limit
• Very bright initially, and slow
decay in brightness due to
cobalt  iron conversion
• Brightness estimated,
standard candle.

hence

Doppler Effect
• Approaching
vehicle’s
whistle blows with higher
pitch.
• The receding vehicle’s
whistle has lower pitch.
• The frequency of the
whistle is the same.
• We hear different notes
because of the motion.

Determining Stellar distance
from Doppler Shift
• Comparing wavelengths
of the absorption lines of
stars with those in the
laboratory frame, we can
find whether the star is
approaching
us
or
receding from us.
• Entire pattern needs to
be compared for this.

Hubble’s Law
vH D
v  recessiona l velocity
H  Hubble Constant (73 km/s/Mpc)
D  Distance

• Edwin Hubble in 30’s found that all the far off galaxies show red shift
indicating that they all are receding away from us.
• Farther the galaxy, they recede faster.
