EXO 023432-5232.3 - an eclipsing AM Herculis binary
The authors report observations of the serendipitous EXOSAT source EXO 023432-5232.3 which confirm that the object is an AM Herculis type binary and show the presence of eclipses by the companion star. From high-speed ...
Spectropolarimetry of the 3-micron ice band in Elias 16 (Taurus Dark Cloud)
Polarization data between 1.2 and 3.8 μm, including spectropolarimetry in the 3-μm ice feature, are presented for the highly reddened field star Elias 16 in the Taurus Dark Cloud. The polarization is observed to increase ...
Interstellar polarization in the dust lane of Centaurus A (NGC 5128)
Optical and infrared linear polarization measurements of the Type 1 supernova 1986G in Centaurus A are used to determine the wavelength dependence of polarization produced by transmission of radiation through the dust lane ...
Polarimetric mapping of a new infrared reflection nebula GGD 27 IRS
We report the discovery of an infrared reflection nebula GGD27 IRS, near the optical nebulosity GGD27. It shows a dumbbell-shaped structure with large degrees of polarization, up to 64%, in the K band. From the centrosymmetric ...
Magnetic field structure in dark clouds

A high resolution hydrogen-line survey of Messier 31. III : H I holes in the interstellar medium
An analysis is carried out of H I holes in M 31 as detected with the Westerbork radiotelescope. The holes range from 100-1000 pc across and represent missing masses ranging from 1000-10 million solar masses, which would ...
Laser guiding of electron beams in the advanced test acceleration
The recently demonstrated technique of laser guiding has been used to propagate successfully a 10-kA relativistic electron beam 95 m through the Advanced Test Accelerator and postaccelerator beamline. The maximum transverse ...
