The possible existence of the June Lyrid meteor shower is examined from data in the IMO archive from 1984 to 1997. It is concluded that the activity is weak but...
On the Extended Structure of the Phoenix Dwarf Galaxy
We present the star formation history (SFH) and its variations with galactocentric distance for the Local Group dwarf galaxy of Phoenix. They have been derived...
On the Extreme Positive Feedback Star-forming Mode from Massive and Compact Super Star Clusters
The force of gravity acting within the volume occupied by young, compact, and massive super star clusters is here shown to drive in situ all the matter...
On the Extreme Positive Star Formation Feedback Condition in Scuba Sources
We present a detailed study of the hydrodynamics of the matter reinserted by massive stars via stellar winds and supernovae explosions in young assembling...
On the Extreme Stationary Outflows from Super Star Clusters: From Superwinds to Supernebulae and Further Massive Star Formation
Here we discuss the properties of star cluster winds in the supercritical, catastrophic cooling regime. We demonstrate that catastrophic cooling inhibits...
On the far infrared bands associated to the vibration of multishell fullerenes
Multishell fullerenes could be produced in the circumstellar envelopes of rich carbon giants as proposed by Ugarte (1995) and could be carriers of diffuse...
On the far-infrared metallicity diagnostics: applications to high-redshift galaxies
In an earlier paper we modelled the far-infrared emission from a star-forming galaxy using the photoionization code CLOUDY and presented metallicity sensitive...
On the Feedback from Super Stellar Clusters. I. The Structure of Giant H II Regions and H II Galaxies
We review the structural properties of giant extragalactic H II regions and H II galaxies based on two-dimensional hydrodynamic calculations and propose an...
On the fine structure of sunspot penumbrae. I. A quantitative comparison of two semiempirical models with implications for the Evershed effect
Sunspot penumbrae exhibit prominent fine structure. Different interpretations of spectropolarimetric observations suggest different, sometimes contradictory...
