  39. How do we find distances beyond the parallax limit? Distance Modulus

  40. Distance Modulus Light spreads over wider area. Makes furthest stars look faint.

  41. Distance Modulus Light spreads over wider area. Makes furthest stars look faint. apparent magnitude m Absolute Magnitude M d = 10 pc M = m

  42. Distance Modulus d < 10 pc M > m d > 10 pc M < m apparent magnitude m Absolute Magnitude M d = 10 pc M = m

  43. Distance Modulus - M = m + 5 5 log d

  44. Stars that Show Parallax

  45. Distance Modulus - M = m + 5 5 log d

  46. Distance Modulus - M = + 5 5 log 11.1 1.32

  47. Distance Modulus - M = 16.1 5 0.12057

  48. Distance Modulus - M = 16.1 0.60287
