| ## Eclipsing variables (ecl) | ||
|
|
||
| Eclipsing variables are binary stars systems in which the orbital plane lies nearly in the line of sight of the observer. The binary components pass in front of one another from observer's perspective and so their combined brightness decreases periodically. | ||
|
|
||
|
There was a problem hiding this comment. Maybe say something here briefly about the eclipses can be different shapes and depths, which you get to below? |
||
| ### Classification and numbers | ||
| - Supertypes | ||
| - variable | ||
| - periodic | ||
| - Subtypes | ||
| - EA | ||
| - EB | ||
| - EW | ||
| - Occurrence rate: very common, about 10<sup>6</sup> expected in ZTF data | ||
|
|
||
| ### ZTF light curves | ||
|  | ||
|
|
||
| #### Description | ||
| Eclipsing variables show regular, periodic "V-shape" dips in their phase folded light curves, which may be sharp or rounded, depending on the system. Their periods may range from minutes to years. Eclipse amplitudes vary from ~0.1 to several magnitudes. | ||
|
There was a problem hiding this comment. Is it just survey sensitivity that prevents us from going below ~0.1? Maybe we explicitly call that out as for ZTF then. |
||
|
|
||
| #### Light curve characteristics | ||
| - periodic variable | ||
| - Range of amplitudes (~0.1 to >1 mag) | ||
| - Periods (from minutes to years) | ||
