Evolved stars observed within the Penn State - Torun Center for Astronomy Planet Search (PTPS) conducted with the Hobby-Eberly Telescope are supposed to present various effects of activity. In addition to chromospheric activity and/or pulsations one may expect spots temporarily appearing on their surfaces and rotating with stars that mimic

We present a design for the computer systems which control, configure, and monitor the Atacama Large Millimeter Array (ALMA) correlator and process its output. Two distinct computer systems implement this functionality: a rack- mounted PC controls and monitors the correlator, and a cluster of 17 PCs process the correlator output into raw spectral

Photometric and radial velocity amplitudes and amplitude related parameters of Galactic single mode classical Cepheids are given complemented with indication of spectroscopic [Fe/H] value, binarity and the pulsation mode. (1 data file).

We present ALMA observations of the mid-J 12CO emission from six single-dish selected 870-μm sources in the Extended Chandra Deep Field-South and UKIDSS Ultra-Deep Survey fields. These six single-dish submillimetre sources were selected based on previous ALMA continuum observations, which showed that each comprised a blend of emission from two or

In this work we try to identify if there exist specific patterns in the orientation of Roman towns and military settlements across the Roman Empire, and whether this can be explained by astronomy, as suggested in a number of ancient texts and latter discussed by contemporary scholars. In order to check if cosmology was present in the urban planning

The β Cephei star HD 180642 was observed by the CoRoT satellite during a run of 156 days in 2007. The space white light photometry revealed the rich frequency spectrum of the star (Degroote et al. 2009). In the present study, we provide additional information on the target, based on both ground-based multi-colour photometry and high-resolution
