      The Infrared Astronomical Satellite (IRAS) opened up the infrared sky and allowed the first statistical studies of disks to be made (Strom et al. ). Shortly thereafter the first sensitive detectors at millimeter wavelengths showed that many disks contained enough material to form planetary systems on the scale of our own (Beckwith et al ~lah/review/   massive star formation.

      Star Formation and the Interstellar Medium in the Milky Way 58 59 provides knowledge of the physics and initial conditions required for star formation, protostellar evolution, and the formation of solar systems like our own.

      The physical conditions in molecular clouds control the nature and rate of star formation, with consequences for planet formation and galaxy evolution. The focus of this review is on the conditions that characterize regions of star formation in our Galaxy. A review of the tools and tracers for probing physical conditions includes summaries of generally applicable results.

The first 2 years of this program were used to make mid-IR observations of regions of star formation in the Orion nebula with the UCSD mid-IR camera at the UCSD/University of Minnesota telescope at Mt. Lemmon. These observations attempted to make the first systematic study of an extended region, known to have newly forming stars, and expected to have complex mid-IR :// J/abstract.

Methods of measuring gas contents and star-formation rates are discussed, and updated prescriptions for calculating star-formation rates are provided.

We review relations between star formation and gas on scales ranging from entire The idea that the star formation rate (SFR) and gas density should be related started with a simple hypothesis stated in a key paper by Maarten Schmidt: “It is assumed that the rate of star formation varies with a power n of the density of interstellar gas.” Schmidt supported his assertion with observational data of the solar Research in Astronomy and Astrophysics is an international journal publishing original We analyze the feasibility of estimating the stellar mass of galaxies by mid-infrared luminosities based on a large sample of galaxies such as the intrinsic extinction, metallicity and star formation rate.

To remove the effect of star formation   evolution in various ways and one such aspect is star forma-tion in a galaxy. Since the early seventies, several theoretical and observational studies have been conducted to understand how star formation in a galaxy is altered or affected by collisions and mergers (Larson &   Buckminsterfullerene (C60) was recently confirmed as the largest molecule identified in space.

However, it remains unclear how and where this molecule is formed. It is generally believed that C60 is formed from the buildup of small carbonaceous compounds in the hot and dense envelopes of evolved stars. Analyzing infrared observations, obtained by Spitzer and Herschel, we found that C60 is   Cosmic Infrared Background and Early Galaxy Evolution (τ ∼ ) indicating unexpectedly early star formation (z ∼ 20).

Early simulations demonstrate that the exoplanet HR e will often perturb its exo-asteroids towards the inner system (Contro et al., ), suggesting that a progenitor architecture of polluted white dwarf systems, one which is similar to the Solar System, is not unusual.

Again, high spatial resolution is a key observational requirement, since star-forming regions are extremely crowded. Formation of planetary systems
