# Pulsating White Dwarfs

## TL;DR

This paper discusses the significant increase in known white dwarfs and pulsating white dwarfs due to SDSS, introduces new types of variable white dwarfs discovered, and highlights novel phenomena observed with Kepler, such as outbursts.

## Contribution

It reports the expansion of known white dwarf varieties and the discovery of new pulsating phenomena enabled by recent surveys and space missions.

## Key findings

- Increased number of known white dwarfs and pulsators
- Discovery of new variable white dwarf types
- Observation of outbursts in pulsating white dwarfs

## Abstract

The Sloan Digital Sky Survey has allowed us to increase the number of known white dwarfs by a factor of five and consequently the number of known pulsating white dwarfs also by a factor of five. It has also led to the discovery of new types of variable white dwarfs, as the variable hot DQs, and the pulsating Extremely Low Mass white dwarfs. With the Kepler Mission, it has been possible to discover new phenomena, the outbursts present in a few pulsating white dwarfs.
