| Summary:
Dipper stars are extrinsically variable stars with deep dimming events due to
extended, often dusty, structures produced by a wide range of mechanisms such
as collisions, protoplanetary evolution or stellar winds. ASAS-SN has
discovered 12 dipper-like objects as part of its normal operations. Here we
systematically search the $sim 5.1$ million ASAS-SN targets with $13<g<14$~mag
for dippers with $Delta gge0.3$~mag to identify 4 new candidates. We also
discover 15 long-period eclipsing binary candidates. We characterized the 19
new and 12 previously discovered objects using the ASAS-SN light curves and
archival multi-wavelength data. We divide them into three categories:
long-period eclipsing binaries with a single eclipse (13 total), long-period
eclipsing binaries with multiple eclipses (7 total) and dipper stars with dust
or disk occultations (11 total).
