41. The Local Interstellar Medium Eventually it runs into the local interstellar medium (LISM). The interaction region between the solar wind and LISM is the subject of Section 2.3, http://solarphysics.livingreviews.org/Articles/lrsp-2004-2/articlesu2.html

The local interstellar medium The solar wind does not expand forever. Eventually it runs into the local interstellar medium (LISM). The interaction region between the solar wind and LISM is the subject of Section , and it is through analogous interaction regions around other stars that solar-like stellar winds can be detected (see Section ), but before the wind/ISM interaction regions are discussed, it is necessary to review the properties of the undisturbed LISM. The principle method by which one studies the ISM is by observing absorption lines that interstellar material produces in spectra of distant stars. These studies reveal that ISM column densities remain rather low within about 100 pc of the Sun in most directions and then increase dramatically ( Sfeir et al. ). This low density region is called the Local Bubble . Figure shows a map of the Local Bubble in the Galactic plane ( Lallement et al. ).

Star Formation and the Interstellar Medium Low-Mass SF High-Mass SF ... Visitors Welcome to the Star Formation division at the AIP! Our research is dedicated to the study of the formation of stars and the evolution of the interstellar medium in our own galaxy, in other nearby galaxies, and also in the early universe. We are interested in the processes driving and influencing both the formation of stars (environment, metallicity, etc.) and the subsequent formation of planets around these stars. Therefore, we focus on the following fields: Low-mass Star Formation High spatial resolution multiplicity and circumstellar disk studies of young stars (T Tauri stars and Herbig Ae stars) Studies of the initial stellar mass function in the Orion Trapezium cluster and the LMC starburst cluster R136 (30 Doradus; in collaboration with the Galaxies division of the AIP) Search for very low-mass stars and brown dwarfs in the Solar neighbourhood and in young clusters/associations (in collaboration with the X-ray division and the LBT project of the AIP) Search for giant planets around white dwarfs (in collaboration with the Stellar Physics division of the AIP) The image shows the resolved nearest binary brown dwarf in the infrared (for more details see here High-mass Star Formation Origin of massive stars in clusters and in the field (in collaboration with the

Home Research Faculty The Interstellar Medium Astrophysics Jeffrey Linsky likes to solve galactic puzzles. Together with his research group, known as the "Cool Star Mafia," he recently figured out why concentrations of deuterium, a heavy form of hydrogen, vary in our galaxy. Most of the universe's deuterium was created during the Big Bang 14 billion years ago. Scientists have known for some time that the region of space near our Sun has higher concentrations of deuterium than other parts of the Milky Way. In 2004, Linsky's group explained why: supernova explosions have blasted deuterium atoms and molecules out of carbon-rich dust grains (which tightly bind them in other, less active regions of the galaxy). Once freed from the dust grains, deuterium mixes with clouds of regular hydrogen. Because our solar system has experienced several nearby supernovae in recent history, concentrations of deuterium are relatively high near us. Scientists believe that studies like Linsky's will help them develop a detailed picture of the chemical evolution of our galaxy. Infrared light absorption by H Chris Greene has successfully predicted the rate of one of the most important chemical reactions that occur in interstellar clouds. He has analyzed the dissociative recombination of a simple polyatomic molecules H

Other Free Encyclopedias Science Encyclopedia Science Encyclopedia Vol 3 Interstellar Matter - Components of the interstellar medium, Significance of the interstellar medium On a clear winter night go outside to a dark location and look for the constellation Orion, the hunter. A row of three stars makes up his belt. Hanging from his belt is his sword, a smaller row of three fainter stars. If you look at the center star in the sword with a pair of binoculars or a small telescope , you will see a small fuzzy patch of interstellar gas and dust, called the Orion Nebula. Space is not empty. The matter in the space between the stars is called interstellar matter or the interstellar medium. The interstellar medium consists of atoms , ions, molecules, and dust grains. It is both concentrated into clouds and spread out between stars and the clouds. The interstellar medium is tenuous enough to qualify as a vacuum on the earth , but it plays a crucial role in the evolution of the galaxy . Stars are born out of the interstellar medium, and when stars die they recycle some of their material back into the interstellar medium. Components of the interstellar medium The interstellar medium can be broadly classified into gas and dust components. The average

Previous session Next session Session GM1 - Mini-Conference on Turbulence in the Interstellar Medium and Solar Wind IV. ORAL session, Tuesday afternoon, November 16 Grand Crescent, The Westin Seattle Magnetic Field Dissipation in the Interstellar Medium Ellen Zweibel (JILA/U. Colorado) There is strong phenomenological evidence that magnetic reconnection occurs in the interstellar medium. In particular, if there is a galactic dynamo there must be magnetic reconnection. But the magnetic Reynolds number R_m is very large for most interstellar structures, typically 10^15 - 10^20, suggesting that the magnetic reconnection rate does not scale as a power of R_m. Furthermore, interstellar magnetic fields are near equipartition with the turbulent velocities, suggesting that reconnection is dynamical as opposed to kinematic. I will discuss physical effects beyond MHD that could enhance the interstellar reconnection rate: ion-neutral drift, collisionless effects, and charged dust.
