... The Vela pulsar was the first discovered in the southern hemisphere (Large et al., 1968) and in an exciting rush of papers was shown to be slowing down, having a polarization sweep across the pulse and to glitch (Radhakrishnan et al., ... Whilst the Vela X nebula had been imaged in great detail at 20 cm by Bock et al. (1998; 2002) and the VLA had imaged the region around the pulsar at 6 cm (Bietenholz et al., 1991) no arcsecond observations close to Vela had been undertaken at the ATCA. ... 2002). ...

... The star formation rate (SFR) of the current SF episode can be estimated from the total H luminosity. ... For the derived total flux F (H )=5.8 erg s -1 cm -2 we obtain a total H luminosity of 10 39 erg s -1 . ... The total mass of ionized gas can be obtained from the average mass density inside the H II region and its volume. An average mass density corresponding to the average electron density of 1 cm -3 within a volume with a diameter of 0.5 kpc yields a total ionized gas mass of 10 6 . ...

... More recently, I have been concerned with observing masers located in the circumstellar shells generated by red giant stars in their mass-loss phase, and in what we can therefore learn about the late stages of stellar evolution. 100 mJy are now undetectable after ~12 years, aka the DEATH of an OH/IR star or its cyclical evolution back to a Mira variable. ... I find that this momentum flux is sufficient to support the largest observed rates of AGB mass-loss. last updated: 14 January 2015 . ...

... During a magnetospheric substorm the cross-tail current is disrupted (e.g., Fairfield and Ness, 1970). A current system called the substorm current wedge (SCW; Atkinson, 1967; McPherron et al., 1973) is formed as this current is diverted through a circuit consisting of earthward (downward) field-aligned currents (FACs) on the eastern side of the wedge, a westward auroral electrojet in the ionosphere , and tailward (upward) FACs on the western side of the wedge. ...

... What work is currently being done to improve the flux calibration accuracy for echelle modes? ... Starting early in Cycle 11, monthly offsetting for echelle modes was turned off to minimize these types of calibration problems. ... We are currently working on redetermining the echelle flux calibration so that it is self-consistent with the 2-D scattered light algorithm. Time dependence of the sensitivity - Sensitivity-monitor data for the echelle modes are currently under investigation. ...

... Files in red?history) . ... Auroral Currents . 25H. Birkeland Currents . ... As noted earlier Kristian Birkeland, reporting in 1903 on his expeditions to the auroral zone, proposed that magnetic disturbances accompanying the aurora were caused by large electric currents flowing down the length of auroral formations. ... In later years these currents became known as the auroral electrojets , and considerable debate ranged over their cause and the way their circuit might be completed. ...

... According to the current estimates, a few percent of Main Sequence B5-F5 stars reveal strong surface magnetic fields reaching the values of tens of kilogauss, which is an order of magnitude greater than the maximal magnetic field in sunspots. ... An important direction in the study of magnetic stars is the study of binary and multiple systems with magnetic components using the techniques of spectroscopy and high angular resolution interferometry. ...

This lesson is intended as a revision of basic direct-current (DC) circuits . It was discovered in the 19th century that certain materials (so-called ideal resistors) have a current through them I that is proportional to the potential difference (voltage) across them V. This is not a fundamental law of physics (like momentum conservation) but is an observed behavior which some materials roughly follow (like the friction law we covered earlier in the course). ... This equation is called Ohm's law. ...
