This PDF by Nora Mills Boyd, Siska De Baerdemaeker, Kevin Heng,
and Vera Matarese is an explication of how the theory and observation balance
within astrophysics. Items under discussion include laboratory astrophysics, the
problem with the Hubble constant, and also how theory plays a game of
give-and-take with observation in stellar population synthesis. Discussions on
epistemological lessons extracted from gravitational-wave astrophysics are also
present, covering simulation practices, idealisations in computer modeling, and
verification of data. Discussing the philosophical implications of observational
black hole astrophysics and entity realism in extragalactic studies, it ends
with reflections by a theoretical astrophysicist, providing an all-encompassing
view into the foundations and methodologies that guide todays astrophysical
research.

Authored by Jes K. Jurgensen, Arnaud Belloche and Robin T. Garrod, this
PDF delves into the role that astrochemistry plays in the process of star
formation. Recent advances and challenges in the field are addressed, with a
focus on chemical inventories in star-forming regions. Chemical differentiation
and the evolution of the protostar under physical conditions are addressed by
the authors, who underscore fractionation as one of the processes. The
communication of physical and chemical aspects of star formation is made by the
document as it exposes the reader to such complicated interactions which finally
end in the emergence of stars and development of chemical complexity in space.

Astrochemistry Lecture Note Prepared by Adwin Boogert Herschel Science
Center - NASA A short lecture note. Kind of a nice basic course on
astrochemistry, though: the chemistry of interstellar space, chemical reactions
in space, techniques for observing interstellar molecules, evolution of the
molecule and its implications for astrobiology.
