Question 1: The Solar Twin Search So Far: Solar twins have been selected on the basis of specific observational parameters, and there are a large number of these to choose from.

[1A] How have the following parameters been employed in the solar analog hunt to date, and what has been the success or failure in identifying solar analogs in terms of those parameters?

Moderators evaluated their group's response and ranked the opinions on a scale of 5 (highly successful) to 1 (completely unsuccessful), or zero (not applicable). In addition, they noted the level agreement among the group by a sigma that ranged from zero (unanimous agreement) to three (significant disagreement). In the table below, we list the twenty parameters given to the groups for discussion. Each group evaluated four parameters, so that each parameter was evaluated independently, in the morning and afternoon, by two different groups of astronomers.

[1B] Are there any relevant parameters that have so far been ignored (both in the literature and in the list of 20 parameters supplied to the working groups) or inadequately considered, and what would be the specific insights gained from considering them? Determine up to two that are most important.

Working groups were asked to select one or two of the most important neglected parameters in the solar analog hunt so far, and to summarize the specific insights to be gained from using those parameters as selection criteria. The results are compiled in Table 2 below. Each parameter is lsited in a separate row, with the number of groups mentioning it and their remarks included in the second and third columns.

Question 2: The Solar Twin Search Following This Workshop: What is the optimum method for searching for solar twins?

[2A] Which, if any, parameters must be used in any search for solar twins (determine up to four)?

Groups listed up to four parameters they considered essential in future searches for solar analogs and twins. Again, a one-to-five scale was used to indicate the level of agreement (or lack thereof) among the group members.

[2B] Do the parameters employed depend on the research needs of the investigator, e.g., would an investigator working with UV data have fundamentally different search criteria than one working in the IR?

Question 3: Optimum Candidates Rank the following stars (listed by HD number) in order of preference as solar twins, to the extent that the working group considers feasible and/or useful. Each group may add up to 2 stars to the list. The stars are: 1835 (9 Cet), 11131, 20630 (kappa Cet), 28099 (VB 64), 44594, 76151, 86728, 89010, 114710 (beta Com), 144585, 146233 (18 Sco), 186408 (16 Cyg A), 186427 (16 Cyg B), 187923A, 217014 (51 Peg).
