Throughout history, we have pondered the ultimate question about why we are here and if we are alone. Carl Sagan eloquently captured this spirit when he said, "Who are we? What are we? We find that we inhabit an insignificant planet of a hum-drum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people." In my dissertation talk, I will discuss the results of my efforts in answering a small piece of this puzzle on the nature of the families of solar-type stars. How often do they have companions (other stars), and how often do they have children (planets)? In the most comprehensive effort yet on this study, I have analyzed 454 stars by synthesizing the vast body of knowledge about these stars and augmenting them with targeted new observations. The resulting statistics show that about 55% of solar-type stars are even more Sun-like, for they are single. This reverses previous expectations that placed our Sun in the minority group. Other results, consistent with expectations, show that younger stars are more likely to have companions, as are more massive stars. An intriguing preliminary result suggests that brown dwarfs, objects too massive to be planets but not massive enough to be stars, form more like planets than like stars, at least when they are companions to stars. Stellar binaries seem to disproportionately favor twins, i.e. stars of nearly identical masses. Closer to home, the results show that planets are as likely to form around single stars as they are around components of binary or multiple star systems. Astronomers are more optimistic than ever that Earth-like planets might be quite common, and these results enhance this optimism by increasing the real estate available for planets, and perhaps life.
