SN2014J  in  M82  (Spring  2014)  

As  part  of  the  Pro-­‐Am  White  Dwarf  Monitoring  (PAWM)  project,  we  searched  for  Earth-­‐sized  planets  transi?ng  white  dwarf  (WD)  stars  in  their  habitable  zones.  Professional  and  amateur  collaborators  observed  a  list  of  bright  WDs,  maintaining  a  con?nuous  baseline.    •  Harvard  observed  a  total  of  75.8hrs  and  contributed  

16  lightcurves  •  No  transits  were  detected  but  variability  was  no?ced  

in  some  WDs.    Below:  a  lightcurve  observed  with  the  Clay  Telescope  by  HOP,  processed  with  MaximDL  and  fit  by  Bruce  Gary  and  PAWM

Asteroids  and  Exoplanets    (Fall  2012)  

We  joined  the  KELT  (Kilodegree  Extremely  Li_le  Telescope)  follow-­‐up  team.  KELT  is  searching  for  transi?ng  exoplanets  around  bright  (V<10)  stars.      •  Many  transit  a_empts  were  aborted  due  to  

bad  weather.  Candidates  we  successfully  observed  were  false  posi?ves  (which  is  also  helpful  to  the  team)  

     

 We  also  began  observing  bright  asteroids  to  refine  orbital  posi?ons  (i.e.  submit  to  the  Minor  Planets  Center).    •  We  were  successfully  able  to  to  detect  

asteroids  as  as  faint  V~17  and  refined  our  techniques

Goals  

Graduate  Students  •  Experience  mentoring  and  working  

with  undergraduates    •  Teaching  experience  •  No  prior  telescope  experience  

required:  gain  skills  in  observa?onal  astronomy  

 Undergraduate  Students  •  No  experience  required:  any  student  

can  have  an  opportunity  to  learn  about  observa?onal  astronomy  

•  Small  groups  (<  6  students):  plenty  of  opportunity  to  engage  in  conversa?on  with  graduate  students  

We  observed  SN2014J  from  January  to  May  in  B,  V,  R,  I  and  H-­‐alpha.  We  used  Maxim  DL  to  make  a  mul?-­‐color  light  curve  of  the  supernova  (see  poster  by  M.  McIntosh  121.17).    Below:  before  and  aler  images  of  M82  

•  Know  your  telescope:  learn  the  limita?ons  of  equipment  and  solware  

•  Plan  ahead:  research  projects  ahead  of  ?me  and  prac?ce  observa?ons  

•  Rally  the  troops:  student  interest  is  high,  many  grad  student  volunteers  needed  

•  Train:  graduate  volunteers  may  not  be  experiences  

 

Lessons  learned  

The  Clay  Telescope  •  Located  atop  Harvard  University’s  Science  Center  •  DFM  16”  Equatorial  Mounted  Telescope  •  Apogee  Alta  U47  CCD  camera    (1024  x  1024  pixel)  

•  13’  x  13’  FOV  •  Bessell  UBVRI  and  H-­‐alpha  filters  

•  SBig  SGS  spectrograph  with  SBig  ST7-­‐XME  CCD  camera  a_ached  with  3  resolu?ons  available  

•  Analysis    and  image  processing  done  with  MaximDL  5  

Observing  strategy  •  Open  sign  ups:  any  undergraduate  can  sign  up  for  an  evening’s  

observa?on  •  Student-­‐run  observa?ons:  undergraduate  volunteers  operate  

telescope  and  do  real-­‐?me  data  reduc?on  and  analysis  ,  under  guidance  of  a  graduate  student  

 

 The  Harvard  Observing  Project  (HOP)  engages  undergraduate  students  in  observa8onal  astronomy  and  gives  graduate  students  extra  teaching  experience  beyond  their  required  teaching  fellowships.        This  project  allows  students  to  see  if  they  are  interested  in  astronomy,  introduces  them  to  scien?fic  research,  and  provides  an  opportunity  for  them  to  interact  with  graduate  students  in  an  informal  sepng.  Observa?ons  are  made  using  the  16”  Harvard  Clay  Telescope.     Clay  Telescope:
