Changes in the Earth s climate depend most basically on changes in the Sun s output the Earth s reflectance and greenhouse gasses Using SoHO helioseismic data a...
Sunspot Decay as Turbulent Erosion of a Magnetic Flux Tube
Decisive evidence is presented against the validity of the conventional linear decay law for sunspots. Preliminary results from a statistical analysis of...
Super massive star clusters: from superwinds to a cooling catastrophe and the re-processing of the injected gas
The presence of compact and massive star clusters is a characteristic property of many starburst and interacting galaxies. Their extreme mechanical and...
Super Star Clusters and Supergalactic Winds: The Case of M82
Recent results from Hubble Space Telescope (HST) have resolved starbursts as collections of small young stellar clusters. We have elaborated tep{Melo04} a...
Super star clusters (SSCs) are young massive objects typically observed in starburst galaxies. They consist of millions of stars occupying volumes only several...
We summarize our results based on observations with the NIRI camera on the Gemini North telescope of three Hii galaxies (Mrk 36, UM 408 and UM 461), obtained to...
