Microlensing by a wide-separation planet: detectability and boundness
Yoon-Hyun Ryu, Myeong-Gu Park, Heon-Young Chang +1
We explore the detection condition of a wide-separation planet through the perturbation induced by the planetary caustic for various microlensing parameters, especially for the siz…
Microlensing Optical Depth Revisited with Recent Star Counts
Yoon-Hyun Ryu, Heon-Young Chang, Myeong-Gu Park +1
More reliable constraints on the microlensing optical depth comes from a better understanding of the Galactic model. Based on well-constrained Galactic bulge and disk models constr…
Around the Clock Observations of the Q0957+561 A,B Gravitationally Lensed Quasar II: Results for the second observing season
Wesley N. Colley, Rudolph E. Schild, Cristina Abajas +35
We report on an observing campaign in March 2001 to monitor the brightness of the later arriving Q0957+561 B image in order to compare with the previously published brightness obse…
'Round the Clock Observations of the Q0957+561 A,B Gravitationally Lensed Quasar
Wesley N. Colley, Rudolph E. Schild, Cristina Abajas +20
An observing campaign with 10 participating observatories has undertaken to monitor the optical brightness of the Q0957 gravitationally lensed quasar for 10 consecutive nights in J…
