... As a result of BTA observations of 23 chemically peculiar stars with strong magnetic fields, it was found that in 22 of them the longitudinal magnetic field, measured from the hydrogen line cores are considerably lower (by about 1/3) than the value measured from metal lines in the same spectra. ... New approaches need to be developed in order to interpret the data. ... The Zeeman spectrum of a star with a strong magnetic field, 53 Cam. ...

. A hydrogen atom and a helium atom go into a bar. The hydrogen atom is clearly upset and moans, "I've lost my electron, my only electron." The concerned helium atom says, "Just calm down now ... are you sure you've lost it?" . The hydrogen atom replies, "Yes, I'm positive!" . (Later, a neutron walks in to the same bar. He sits down and says to the bar tender, "Hey, how much for a beer?" The bar tender looks at him and says, "For you, no charge!")

We present the detection and analysis of molecular hydrogen emission towards ten interstellar regions in the Large Magellanic Cloud. We examined low-resolution infrared spectral maps of 12 regions obtained with the Spitzer infrared spectrograph (IRS). ... The excitation diagrams of the detected H2 transitions are used to determine the warm H2 gas column density and temperature. ... We find the excitation of H2 by this process is equally efficient in both atomic- and molecular-dominated regions. ...
