A Search for Analogs of KIC 8462852 (Boyajian’s Star): A Proof of Concept and the First Candidates

Abstract: The seemingly normal F dwarf, KIC 8462852 (a.k.a. Boyajian's Star), has been observed to exhibit two types of behavior unique among known variable stars: infrequent episodes of small brightness dips and a long-term decline in brightness between the dips. No satisfactory mechanism has been found for this behavior, at least in part, because there is only one known example. To begin to rectify this, we have searched for other stars exhibiting similar dipping behavior using the Northern Sky Variability Survey and … Show more

“…Photometric variability caused by circumstellar dust has been found in stars of different types: in rare cases in main sequence stars (Schmidt 2019), and more often in evolved stars (AGB, post-AGB, R CrB). The most diverse manifestations of circumstellar dust can be found in pre-main-sequence stars (TTS, HAeBe) that is related to the active gas-dust discs around them.…”

“…Additionally, ASAS-SN's large longitude coverage allows for observations of the same source by multiple telescopes. As an example, ASAS-SN data has already been successfully used to identify variable stars (Jayasinghe et al 2018(Jayasinghe et al , 2019dPawlak et al 2019;Jayasinghe et al 2019e), derive periodluminosity relationships for δ Scuti stars (Jayasinghe et al 2019a), identify M-dwarf flares (Rodríguez Martínez et al 2019), study contact binaries (Jayasinghe et al 2019b), and to examine the long-term variability of Boyajian's Star (Simon et al 2018) and compare it with the dipper phenomenon (Schmidt 2019). Finally, ASAS-SN has recently identified a potential new "Boyajian's Star" analog exhibiting rapid dimming events, nicknamed Zachy's Star (Way et al 2019).…”

“…These "needles in the haystack" may challenge our understanding of other stars and spark new theoretical developments, such as the case of Boyajian's Star (Boyajian et al 2016;Wright et al 2016;Bodman & Quillen 2016;Foukal 2017;Katz 2017;Neslusan & Budaj 2017;Ballesteros et al 2018;Wyatt et al 2018;Martinez et al 2019;Sucerquia et al 2019). Accordingly, new methods to flag these signals for closer inspection have been developed in recent years to expedite their recovery (Giles & Walkowicz 2019;Schmidt 2019;Wheeler & Kipping 2019).…”
