Manisha Pal,Nripes K. Mandal,Bikas K. SinhaIonization and heating mechanisms are reviewed; some of them apply to the interstellar medium as a whole, others only to localized regions. Cooling processes are briefly summarized. Results are given from a recent model calculation for an intercloud medium heated by X-rays.作者: OASIS 時(shí)間: 2025-3-22 03:38 作者: invulnerable 時(shí)間: 2025-3-22 07:29 作者: 人類(lèi)學(xué)家 時(shí)間: 2025-3-22 12:32
An Overview of Triticale Doubled Haploids,Observations have been made at 21 cm with a resolution of 11′ to look for fine structure in the polarization distribution. In the North Polar Spur, the angular scale of the polarization parameters varies with latitude. This is attributed to an increase in the irregularity of the magnetic field in the Spur with latitude.作者: 任命 時(shí)間: 2025-3-22 15:32
Nano-Fluids, Next-Generation Heat TransferWe have investigated the gas-to-dust ratio in the Galaxy by comparing 21-cm H. column densities with the color excesses of globular clusters. We find a constant gas-to-reddening ratio in interstellar clouds and the intercloud medium. This ratio is also independent of galactic latitude.作者: 任命 時(shí)間: 2025-3-22 18:37 作者: SEED 時(shí)間: 2025-3-22 22:16
Two New Recombination-Line ResultsThis paper reports two new recombination-line results. The first is the detection of carbon line emission from the dark cloud near ?

Theoretical Calculations of Interstellar Cloud FormationNumerical calculations of the growth of thermal instabilities show that condensations tend to form with the proper sort of density contrast but the wrong shapes (and, to some extent, sizes) to qualify as the observed interstellar clouds analyzed by Heiles.作者: 馬籠頭 時(shí)間: 2025-3-23 10:35 作者: 瑣碎 時(shí)間: 2025-3-23 14:10 作者: DEI 時(shí)間: 2025-3-23 21:00 作者: Endoscope 時(shí)間: 2025-3-23 22:11
