SECOND ANNOUNCEMENT


University of Barcelona Conference on

RADIO EMISSION FROM THE
STARS AND THE SUN

3-7 July 1995
Barcelona, Spain

This second announcement contains details of the scientific program, registration and accommodation for the meeting. We request that you fill in the appropriate forms at the end of this bulletin and return them by fax or e-mail before the deadlines to the addresses indicated below. This announcement is also being distributed by ordinary mail.

SCIENTIFIC PROGRAM
It has been 10 years since the last meeting devoted to stellar radio emission (Radio Stars: Boulder, Colorado, 1984). Since that time there have been major observational advances in this field. The number of stars and classes of stars that are known to be sources of radio emission have increased dramatically. We are now able to image radio emission from stellar sources at resolution and sensitivity that was impossible 10 years ago. Moreover, there have been new and exciting results in both continuum and spectral line, arising from new telescopes operating at millimeter and submillimeter wavelengths. These data have revealed new phenomena associated with stars and have yielded new observational data on previously known phenomena. It is time to synthesize this rich and powerful set of new radio observations; to bring together workers in this field and to help turn this data into new theories and insights into the processes giving rise to stellar radio emission.

At the same time that major advances have been made in observations of radio stars, the study of solar radio emission has been making tremendous strides, particularly in the area of active phenomena. Observational highlights include i) results from the new Japanese radioheliograph; ii) joint microwave soft X-ray, and hard X-ray imaging of solar flares by the VLA, the Japanese radioheliograph, and YOHKOH; iii) high-time resolution imaging of dynamical phenomena; iv) joint continuum imaging and spectroscopy of decimetric phenomena; v) broadband microwave imaging spectroscopy; vi) mapping at millimeter and submillimeter wavelengths.

Solar and stellar radio astronomers have traditionally worked as two separate communities. Given the significant advances in each area, we have an excellent opportunity to foster cross-fertilization between the two disciplines. One of the goals of this meeting is to bring these two communities together to explore those areas of astrophysics in common and to study the solar-stellar connection.

The conference will consist of invited review talks, which will give a broad and thorough overview of the topics of the meeting, together with shorter, more specific, invited talks. Scientific sessions will take place from 9am to 1:00pm and from 2:30pm to 6:00pm each day of the conference except Tuesday, when sessions will end at 4:00pm. Contributions from participants are welcome, mainly in the form of poster. Only a few 10-15 minute, oral contributions will be scheduled. Plenty of time will be available for poster viewing and discussion.

Barcelona, the site of the 1992 summer Olympic Games, is a Mediterranean city, the capital of the Catalonia country in the northeast of Spain. The city has a long history rooted in the Roman culture, that spans over 2000 years. The Gothic Quarter is particularly nice and lively. The city has many fine examples of the architectural accomplishments of Gaudí, and has many historic buildings and sites. Barcelona is also known for housing most of the best paintings of Picasso and Miró. The weather conditions in Barcelona in July are usually hot and sunny. The average temperature is C and humidity is normally high.
