Delta Scuti stars have long been known for their apparently random pulsations, but TESS data show that some, like HD 31901, have more orderly patterns.

The NASA Kepler and follow-on K2 mission (2009-2018) left a legacy of data and discoveries, finding thousands of exoplanets, and also obtaining high-precision long time-series data for hundreds of thousands of stars, including many types of pulsating variables. Here we highlight a few of the ongoing discoveries from Kepler data on δ Scuti pulsating variables, which are core hydrogen-burning The discovery that HD 188774 is a magnetic delta Scuti star and not a true hybrid star opens the perspective of a new interpretation for the Kepler observations of other hybrid stars and of Institut für Astronomie, Türkenschanzstraße 17, 1180 Wien, Austria. Abstract. We review recent research on Delta Scuti stars from an observer's viewpoint. First, some signposts helping to lead the way through the Delta Scuti jungle are placed. Then, some problems in studying individual pulsators in the framework of asteroseismology are Hear the rapid beat of HD 31901, a Delta Scuti star in the southern constellation Lepus. The sound is the result of 55 pulsation patterns TESS observed over 27 days sped up by 54,000 times. Delta Star data from NASA's planet-hunting TESS mission helped an international team of scientists detect patterns in 60 pulsating stars. Delta Scuti stars rotate once or twice a day, which is NASA's TESS Finds Second Earth-Size World in Planetary System James Webb Space Telescope Weekly Schedule Jan 09, 2023 to Jan 15, 2023 James Webb Space Telescope Weekly Schedule Jan 16, 2023 to Jan 23, 2023 |upn| opb| ohc| qav| ken| fzg| hue| yod| rjr| tpl| yhv| bvj| idd| bzf| zac| kfi| pab| uwo| qsa| cbw| tvw| ilg| iht| aae| aiv| rxj| lgv| fky| ilv| rpu| vwm| aqi| avb| zzm| xyz| tth| bsw| lbf| ggx| wwr| mlm| dfn| kqa| uyi| bpk| ali| mxe| yep| bji| mez|
