In the disk of our Galaxy, about four solar masses of interstellar matter (ISM) per year are transformed into stars. Observations combined with evolutionary models (see also, e.g., Shu et al., 1987) suggest the following sequence of events for the formation of medium- and high-mass stars, which is illustrated by the Orion Giant Molecular Cloud (OMC; see Figure 1): 1. In an extended GMC of medium density (Figure 1a; nH ∼ 102 to 103 cm-3) a filament or ridge structure of increased density… 

IRAS 18317–0757: A Cluster of Embedded Massive Stars and Protostars

We present high-resolution, multiwavelength-continuum, and molecular-line images of the massive star forming region IRAS 18317-0757. The global infrared through millimeter spectral energy

Herbig-Haro objects—tracers of the formation of low-mass stars and sub-stellar objects

Abstract Herbig-Haro objects (HHOs) are caused by outflows from young objects. Since the outflow relies on mass accretion from a circumstellar disk, it indicates ongoing growth. Recent results of

Interferometric Mapping of Magnetic Fields: The Massive Star-forming Region G34.4+0.23 MM

We report millimeter interferometric observations of polarized continuum and line emission from the massive star-forming region G34.4. Polarized thermal dust emission at 3 mm wavelength and CO J = 1→

Directed Panspermia. 3. Strategies and Motivations for Seeding Star-Forming Clouds

Microbial swarms aimed at star-forming regions of interstellar clouds can seed stellar associations of 10 - 100 young planetary systems. Swarms of millimeter size, milligram packets can be launched

Millimetre and Submillimetre Observations of High–Mass Star Forming Cores

I summarize recent millimetre and submillimetre observations of cloud cores where massive star formation is currently taking place. The first systematic continuum surveys in this wavelength range

Seeding the Universe with Life: Securing Our Cosmological Future

Planetary microcosms were constructed using extracts from meteorites that simulate solutions in the pores of carbonaceous chondrites. The microcosms were found to support the growth of complex algal

Astroecology, cosmo-ecology, and the future of life

Experimental astroecology quantifies the amounts of life that can be derived from asteroids in terms of time-integrated biomass, as 10 27 kg-years during the next billion years of the Solar System (a thousand times the 10 24 kg- years to date).


We report on the results of an approximately 90 ks Chandra observation of a complex region that hosts multiple sites of recent and active star formation in ARA OB1a. The field is centered on the



The internal structure of molecular clouds. III : Evidence for molecular depletion in the NGC 2024 condensations

Maps of the star forming region NGC2024 in the mm-wave transitions of C 34 S, C 17 O and C 18 O, obtained at the IRAM 30-m telescope, with angular resolutions of 21″ to 12″ are presented. Using the

Dust emission from star forming regions. II. The NGC 2024 cloud - core revisited.

A previous Paper (Mezger et al., 1988, Paper I) presented first observational evidence for the existence of six compact dust condensations in the dense NGC2024 cloud core. It was suggested that these

CS multitransitional studies of density distribution in star-forming regions. I. The NGC 2071 region

The NGC 2071 molecular cloud was observed in the J = 2 to 1, 5 to 4, 6 to 5, and 7 to 6 transitions of the CS molecule with resolutions of 11 - 24 arcsec. The emission in all transitions peaks

Star Formation in Molecular Clouds: Observation and Theory

Star-formation (SF) processes occurring on the scale of giant molecular clouds (10 to the 6th solar masses and 10 to the 20th cm) or smaller are discussed, reviewing the results of recent theoretical

Dust emission from star-forming regions. III : The Rho Ophiuchus cloud―where are the low-mass protostars ?

We have surveyed the dust emission of the densest part of the Rho Oph cloud as outlined by C 18 O and DCO + line emission and have found three structureless cores of densities n H ∼4 10 5 −10 6 cm −3

Composite interstellar grains

The possibility that interstellar grains are composite collections of very small particles, loosely attached to one another, is investigated. The grains are assumed to include a substantial

The large system of molecular clouds in Orion and Monoceros

Emission is noted over about one-eighth of an 850-sq deg region centered on Orion and Monoceros that has been surveyed in the J = 1 to 0 line of CO; most of the emission arises from giant molecular

Observations of Star-Forming Regions with the Hat Creek Millimeter Array

The 3-element millimeter interferometer at the Hat Creek Radio Observatory has been used to map the molecular line emission from a wide range of star-forming regions, from dark clouds such as B5 and
