  SASI since 1998. She was actively involved as the society&rsquo;s web admi

  talks, participated as a volunteer at the annual Open Nights and has writt
 en several articles for the society&rsquo;s journal.</p><p>As an Informatio

 ion, after attending several astronomy conferences worldwide. She completed
  studies toward a Bachelor of Science degree at Macquarie University in 201
 1 and is finalizing the next stage of her studies at Leicester University i
 n the UK. Her research was focused on the search of companions to white dwa

 text-align: left;">Furthermore, searching for brown dwarfs can also place c

 tors. They also offer a unique opportunity to test properties predicted for
