Gaia20fnr: A binary-lens microlensing event with full orbital motion revealed by four space telescopes

M. Wicker, Ł. Wyrzykowski, M. Hundertmark +49

The microlensing event Gaia20fnr is a long-duration, non-caustic-crossing binary-lens event at high Galactic latitude. Triggered by a photometric rise detected by the Gaia space mi…

Constraining Lens Masses in Moderately to Highly Magnified Microlensing Events from Gaia

U. Pylypenko, Ł. Wyrzykowski, P. J. Mikołajczyk +57

Microlensing events provide a unique way to detect and measure the masses of isolated, non-luminous objects, particularly dark stellar remnants. Under certain conditions, it is pos…

TESS and ground-based observations of WZ Sge-type dwarf novae in outburst

Y. Tampo, N. Kojiguchi, K. Isogai +30

Dwarf nova (DN) superoutbursts are accompanied by superhumps, which change their periods and profiles over a superoutburst. We present the TESS and ground-based observations of nin…

GOTO065054+593624: a 8.5 mag amplitude dwarf nova identified in real time via Kilonova Seekers

T. L. Killestein, G. Ramsay, M. Kennedy +62

Dwarf novae are astrophysical laboratories for probing the nature of accretion, binary mass transfer, and binary evolution -- yet their diverse observational characteristics contin…
