Zodiacal light photopolarimetry. III - All-sky survey from Teide 1964-1975 with emphasis on off-ecliptic features
Photopolarimetric observations of the zodiacal light over a complete solar cycle are used to study the average distribution of brightness and degree of...
ZTF J021804.16+071152.93: a dead cataclysmic variable and potential solution to the missing period bouncer cataclysmic variables
It is predicted that half or more of all cataclysmic variables (CVs) should have evolved past the period minimum and now exist as so-called period bouncers...
ZW 0855+06: A Wolf-Rayet Dwarf Galaxy Triggered by a Dwarf-Dwarf Interaction
We present narrowband (Hα and adjacent continuum) and broadband (B and V) optical images of the dwarf Wolf-Rayet galaxy Zw 0855+06 and its companion, together...
[Mg/Fe] and variable initial mass function: Revision of [α/Fe] for massive galaxies
Observations of nearby massive galaxies have revealed that they are older and richer in metals and magnesium than their low-mass counterparts. In particular...
``Explosion'' and Intensification of Magnetic Flux Tubes
A magnetic flux tube anchored at the bottom of the solar convection zone and rising toward the surface as a result of an undulatory instability can be affected...
