An Introduction to Astrophysics
O'Dell computed the linear radii of a large number of planetaries. Assuming the
sizes of the nebulae to lie between the limit of identification and 0.7 pc, O'Dell
calculates the total number of planetaries in the Galaxy to be 4.8 x 104. More
recent ...

number of planetaries in the Galaxy to be 4.8 X 104. More recent determination
by various authors point to the conclusion that the actual number should be
comparatively less. Planetaries are believed to have heavy concentration around
the ...

It is not impossible, however, that the marked concentration of small planetaries
near 19h is merely fortuitous. Planetary Forms While the details of the forms
assumed by individual planetaries are frequently of bewildering complexity, there
are ...

3.2 M31 Lawrie and Ford (1982) used a Velocity Modulating Camera to observe
45 planetaries within 200 pc of the center of M31. Lawrie (1983) measured the
radial velocities for 33 of the nebulae to derive a systemic velocity of -309 :l: 25

Planetary Nebulae: Observations and Theory
On the question of abundances, what strikes me is that except in the halo
planetaries, there are remarkably small differences in the abundances among
difference planetaries. There are a few Population I planetaries with considerably
higher ...

Furthermore observations of the halo planetaries M31290 and M31-372, for
which Henry (1990) finds logarithmic oxygen abundances [O/H]8 = 8.54 and 8.05
, respectively (on a scale where the logarithmic hydrogen abundance is 12.0), ...

Nevertheless, these planetaries are very interesting visually. Planetary nebulae,
like globular clusters, are not Milky Way objects: they are found in every direction
in the sky. Moreover, like globulars planetaries are more abundant toward the ...
Craig Crossen, Gerald Rhemann, 2004
15.2 Spatial Distribution Although no complete survey of the planetaries in M31
has been published, the partial surveys so far carried out provide good coverage
of much of the galaxy, enough to determine the spatial distribution reasonably ...

One of the more prominent and unusual characteristics of many brighter
planetaries is their “blinking effect” – the instantaneous brightening and dimming
of the nebula that occurs when the observer switches from direct to averted vision
and ...

Nebulae Most nebulae belong to one of the five groups of planetaries, diffuse
nebulae, open and globular star clusters, and galaxies. Planetary nebulae:
These are called “planetaries” because in a telescope they look like small,
