X-WR-CALDESC:On Wednesday\, Mar. 9th\, 2022 at 7 pm (PST)\, Dr. Adam Burgas
 ser (University of California\, San Diego) will give a free\, illustrated\
 , non-technical lecture entitled:  \n\n“Dark Star: The Invisible Universe 
 of Brown Dwarfs' \n        \nAbout this Lecture:\n\nNormal stars\, like ou
 r Sun\, shine because they undergo nuclear fusion\, turning hydrogen into 
 helium and converting matter into radiation. But what if a star wasn't abl
 e to fuse? What would such a 'dud' look like? These were purely theoretica
 l question until the 1990s\, when the first examples of non-fusing stars\,
  or brown dwarfs\, were discovered. Today\, many thousands of such objects
  are known\, spanning a wide range of temperatures and masses\, and they o
 ccupy a unique niche of at the intersection of stars and exoplanets. In th
 is presentation\, Prof. Burgasser will introduce the science of brown dwar
 fs\, discuss how they were and continue to be discovered\, highlight some 
 of their exceptional properties\, and describe how this (mostly) invisible
  population may provide clues to the early formation and evolutionary hist
 ory of the Milky Way. \n \nAbout Adam Burgasser:\n\nAdam Burgasser is a pr
 ofessor of Physics at UC San Diego\, and an astrophysicist who studies the
  coldest stars\, brown dwarfs\, and extrasolar planets. Prof. Burgasser de
 fined the “T spectral class” of brown dwarfs as a graduate student\; and i
 s one of the co-discoverers of the TRAPPIST-1 exoplanetary system\, a syst
 em of seven Earth-sized planets orbiting an object at boundary of the star
 /brown dwarf divide.  He has authored over 600 publications\, including wo
 rk in astrophysics\, physics education\, and equity\, diversity\, and incl
 usion in STEM. Prof. Burgasser is currently a Vice-President of the Americ
 an Astronomical Society and has been a Fulbright scholar. \n\n------------
