KMT-2024-BLG-0404L: A triple microlensing system consisting of a star, a brown dwarf, and a planet
Cheongho Han, Andrzej Udalski, Chung-Uk Lee +29
We have investigated the lensing event KMT-2024-BLG-0404. The light curve of the event exhibited a complex structure with multiple distinct features, including two prominent causti…
An Earth-mass Planet in a Time of Covid-19: KMT-2020-BLG-0414Lb
Weicheng Zang, Cheongho Han, Iona Kondo +56
We report the discovery of KMT-2020-BLG-0414Lb, with a planet-to-host mass ratio ---- at , which is the lowest mass-ratio micro…
EROS 2 photometry of probable R Coronae Borealis stars in the Small Magellanic Cloud
P. Tisserand, J. B. Marquette, J. P. Beaulieu +1
EROS 2 (Experience de Recherche d'Objets Sombres) conducted a survey of the SMC between July 1996 and February 2003 in two EROS broad-band colours, V_E and R_E. The photometric dat…
A 1" Telescope: The Optimal Approach to Bright-Star Planetary Transits
Joshua Pepper, Andrew Gould, D. L. DePoy
Planetary transits of bright stars, V < 10, offer the best opportunity for detailed studies of extra-solar planets, such as are already being carried out for HD209458b. Since these…
EROS 2 proper motion survey: Constraints on the halo white dwarfs
B. Goldman, C. Afonso, Ch. Alard +9
We are conducting a 377-square-degree proper motion survey in the ~V and I bands in order to determine the cool white dwarf contribution to the Galactic dark matter. Using the 250…
Microlens Mass Measurement using Triple-Peak Events
Jin H. An, Andrew Gould
We show that one can measure the effects of microlens parallax for binary microlensing events with three well-measured peaks -- two caustic crossings plus a cusp approach, and henc…
