Past ultraviolet and optical observations of stars hosting close-in Jupiter-mass planets have shown that some of these stars present an anomalously low chromospheric activity, significantly below the basal level. For the hot Jupiter planet host WASP-13, observations have shown that the apparent lack of activity is possibly caused by absorption from the intervening interstellar medium (ISM). Ins...

The Information Spectrum Method (ISM) and the Resonant Recognition Model (RRM) represent a methodology based on signal processing that analyses characteristic spectral motifs in DNA/RNA and protein sequences. Some inconsistencies have been reported recently with regard to the spectral characterization of speciÞc biological sequences utilizing the ISM (RRM) and this motivated examination of the ...

High ambient interstellar pressure is suggested as a possible factor to explain the ubiquitous observed growth-rate discrepancy for supernova-driven superbubbles and stellar wind bubbles. Pressures of P/k ∼ 10 cm K are plausible for regions with high star formation rates, and these values are intermediate between the estimated Galactic mid-plane pressure and those observed in starburst galaxies...

Molecular outflows associated with GL 2591 and W28 A2 were observed in the 492 GHz [C I] line. Upper limits are set on the [C I] emission in the extremely high velocity line wings. These limits are discussed in terms of wind-driven and jet-driven models of molecular outflows. Subject headings: ISM: atoms — ISM: individual (GL 2591, W28 A2) — ISM: jets and outflows — ISM: kinematics and dynamics
