Boyajian, Roi Alonso, Alex Ammerman et al., 2018. _The Astrophysical Journal Letters 853(1), L8_. Results of the crowd-funded 2017 monitoring campaign, mainly with the Las Cumbres Observatory network. Four dips of 1 to 2.5 per cent (named Elsie, Celeste, Skara Brae and Angkor) show no change in the stellar spectrum or polarisation and are deeper in blue light than red, which favours optically thin dust with grains much smaller than 1 micron. **Tabby's star (KIC 8462852)** ArticleCopy of **[Ground-based photometry of the 2017 dips](https://mysteriesdept.com/mysteries/tabbys-star/artifacts/ART0D8E7QJE3QH3/ground-based-photometry-of-the-2017-dips)** doi: **[10.3847/2041-8213/aaa405](https://doi.org/10.3847/2041-8213/aaa405)** Checked against the original0 ## What it's used for here The test that turned the argument towards dust; the source of the dip names and the colour result. ## Cited by on this site 15 records [Ground-based photometry of the 2017 dips](https://mysteriesdept.com/mysteries/tabbys-star/artifacts/ART0D8E7QJE3QH3/ground-based-photometry-of-the-2017-dips) ART [Ground-based photometry of the 2017 dips: document](https://mysteriesdept.com/mysteries/tabbys-star/copies/CPY0D8E7QT81QS2/ground-based-photometry-of-the-2017-dips-document) CPY [Multi-band photometry of the 2017 dips (Las Cumbres Observatory and others)](https://mysteriesdept.com/datasets/DAT0D8E7NC40KBP/multi-band-photometry-of-the-2017-dips-las-cumbres) Dataset DAT [Dips occurred in the Kepler years and again in 2017, with quiet between.](https://mysteriesdept.com/mysteries/tabbys-star/evidence/EVD0D8E7JP67TD3/dips-occurred-in-the-kepler-years-and-again-in-2017-with) Evidence EVD [No change in the stellar spectrum or polarisation was seen during the 2017 dips.](https://mysteriesdept.com/mysteries/tabbys-star/evidence/EVD0D8E7ACJ4717/no-change-in-the-stellar-spectrum-or-polarisation-was-seen) Evidence EVD [The 2017 campaign notes its data may also be consistent with variations intrinsic to the photosphere.](https://mysteriesdept.com/mysteries/tabbys-star/evidence/EVD0D8E7A4R7ZM3/the-2017-campaign-notes-its-data-may-also-be-consistent-with) Evidence EVD [The 2017 dips were chromatic, which large opaque structures would not produce.](https://mysteriesdept.com/mysteries/tabbys-star/evidence/EVD0D8E7B4010M5/the-2017-dips-were-chromatic-which-large-opaque-structures) Evidence EVD [The 2017 dips were deeper in blue than red with no change in spectrum or polarisation; the authors favour…](https://mysteriesdept.com/mysteries/tabbys-star/evidence/EVD0D8E77YE7HJZ/the-2017-dips-were-deeper-in-blue-than-red-with-no-change-in) Evidence EVD [The 2017 dips are shown to be deeper in blue than red](https://mysteriesdept.com/mysteries/tabbys-star/events/EVT0D8E75R45B4Z/the-2017-dips-are-shown-to-be-deeper-in-blue-than-red) EVT [The star dips again, beginning with Elsie in May 2017](https://mysteriesdept.com/mysteries/tabbys-star/events/EVT0D8E75GA4M2X/the-star-dips-again-beginning-with-elsie-in-may-2017) EVT [Sliding-box dip search with injection-recovery for TESS light curves](https://mysteriesdept.com/methods/MTH0DDYEH1HVCN2/sliding-box-dip-search-with-injection-recovery-for-tess) Method MTH [Tabby's star (KIC 8462852)](https://mysteriesdept.com/mysteries/tabbys-star) The mystery article MYS [Las Cumbres Observatory](https://mysteriesdept.com/mysteries/tabbys-star/organisations/ORG0D8E741E3XA5/las-cumbres-observatory) ORG [Has the dipping stopped, or does it come in episodes?](https://mysteriesdept.com/mysteries/tabbys-star/questions/QST0D8E77ET2CAQ/has-the-dipping-stopped-or-does-it-come-in-episodes) Question QST [What blocks the light during the deep, irregular dips?](https://mysteriesdept.com/mysteries/tabbys-star/questions/QST0D8E76FJ6B8S/what-blocks-the-light-during-the-deep-irregular-dips) Question QST ## Cite it ``` Boyajian, T.
