Many barred galaxies show a set of symmetric enhancements at the ends of the stellar bar, called the ansae, or ``handles'', of the bar. In this poster, we make a quantitative analysis of the occurrence of ansae in barred galaxies, making use of The de Vaucouleurs Atlas of Galaxies by Buta and collaborators. We find that ˜40% of SB0s show ansae in

Aims: We present an analytic approximate seismic inversion scheme for damped transverse coronal loop oscillations based on the thin tube and thin boundary approximation for computing the period and the damping time. Methods: Asymptotic expressions for the period and damping rate are used to illustrate the process of seismological inversion in a

Accurate determination of the rotation rate in the radiative zone of the Sun from helioseismic observations requires rotational frequency splittings of exceptional quality as well as reliable inversion techniques. Here we present inferences based on mode parameters calculated from 2088 day MDI, GONG, and GOLF time series that were fitted to

Continuous monitoring of ground deformation in the volcanic island of Tenerife, Canary Islands, is based on GPS networks, since there are as yet no tiltmeter stations installed on the island. However, there is a world-class astronomical observatory on the island, the El Teide Observatory, where four tiltmeters, two aligned in the North-South and

Sigma-drop galaxies are characterized by a drop in the stellar velocity dispersion in their centers. One of the most likely theories to explain this phenomenon is that there is a young stellar population that has recently formed, and that has inherited the kinematics of the gas. We compare the morphology of the dust and the Hα emission in 20 σ-drop

After our tentative detection of an optical counterpart to CXOU J010043.1-721134 from archival Hubble Space Telescope (HST) imaging, we have followed up with further images in four bands. Unfortunately, the source originally identified is not confirmed. We provide deep photometric limits in four bands and accurate photometry of field stars around
