1
Astronomy: A Physical Perspective
For a protostar, the continuous spectrum peaks in the near infrared. The dust in
the collapsing cloud surrounding the protostar will absorb some of the radiation.
The dust will be heated, but will not be the same temperature as the star.

Horizons: Exploring the Universe
Although the term is used rather loosely by astronomers, a protostar can be
defined as a stellar-mass object that is compressed and hot enough to be
opaque to the radiation it is emitting internally but not yet compressed and hot
enough to ...
Michael Seeds, Dana Backman, 2013

Evolution of Interstellar Matter and Dynamics of Galaxies
Although the protostar condenses out between ti and tj , it is buried deep within
the densest part of the layer and cannot be resolved on the scale of Figure Id. In
Figures 2a-d, the density at each particle is plotted against x. The times are the ...

Planetary Science: The Science of Planets around Stars, ...
Such a protostar would have a radius about 1100 au. For such a protostar, the
luminosity from Equation G.1 is 1.6 X 1028 W - or about 40 times the luminosity of
the Sun. Although the protostar has a low temperature, it also has a very large ...

Universe: The Solar System
The Evolution of a Protostar In the 1950s, astrophysicists such as Louis Henyey
in the United States and C. Hayashi in Japan performed calculations that
enabled them to describe the earliest stages of a protostar. At first, a protostar is
merely a ...

Astrophysics is Easy!: An Introduction for the Amateur ...
The dust in the vicinity of a protostar, often called a cocoon nebula, absorbs the
light, and so it is very difficult to observe at visible wavelengths.5 On the other
hand, they can be seen at infrared wavelengths... but this does not really help us,
...
Woolfson's suggestion is that the Sun was formed in a star cluster and that after it
became a main sequence star it had a close passage with a very much larger
protostar. As a result it pulled out some material from the protostar and some of
this ...

Conducting Astronomy Education Research: A Primer
Because it absorbs so much energy from its central protostar, the dust
surrounding a protostar becomes greatly heated to a few hundred kelvins. The
warmed dust then reradiates its thermal energy at infrared wavelengths, to which
normally ...

Discovering the Universe: From the Stars to the Planets
7-3 When a protostar ceases to accumulate mass, it becomes a pre-main-
sequence star Protostars are physically larger than the main-sequence stars into
which they are evolving. A protostar of 1 Mo, for example, has about 5 times the ...
