Triggers

Please expand this section with your favourite types of possible alerts. The most useful information would be the number statistics, amplitude and timescale, example light curve, spectrum and the reasoning for an rapid alert.

Possible triggers for Science Alerts

• Supernovae

• Dwarf/classical novae

• Microlensing events

• M-dwarf flares

• R Coronae Borealis type variables (dimming objects)

• FU Orionis-type eruptive stars

• Other rare transients

Table of transients

This tables is based on Rau et al. 2009 on Palomar Transient Factory (PTF).
