We compare optical and near-infrared colors of disks and bulges in a diameter-limited sample of inclined, bright, nearby, early-type spirals. Color profiles along wedge apertures at 15^deg^ from the major axis and on the minor axis on the side of the galaxy opposite to the dust lane are used to assign nominal colors for the inner disks (at 2 scale

Global Oscillation Network Group data reveal that the internal structure of the sun can be well represented by a calibrated standard model. However, immediately beneath the convection zone and at the edge of the energy-generating core, the sound-speed variation is somewhat smoother in the sun than it is in the model. This could be a consequence of

Helioseismology requires nearly continuous observations of the oscillations of the solar surface for long periods of time in order to obtain precise measurements of the sun's normal modes of oscillation. The GONG project acquires velocity images from a network of six identical instruments distributed around the world. The GONG network began full

We report on narrow-band Hα imaging and long-slit spectroscopy at intermediate resolution from [NeV] lambda3425A to [SIII] lambda9532A at PA=25.˚5 through the nucleus of the Seyfert 2 galaxy NGC 5347. The nucleus shows very-high-excitation lines, such as [NeV], HeII, [FeVII] and [FeX]. At 3 arcsec to the north-east there is a high-excitation

In this paper we present the BV-CCD photometry of three stellar fields of the Large Magellanic Cloud (LMC). They are taken at the center of V-charts of the Hodge & Wright (1967) catalog after which they are named. The fields under examination are LMC-30 (2degNorth-West of the Bar), LMC-45 ( 2degNorth of the Bar) and LMC-61 ( 3degNorth-East of the
