Periodicities in the K2 light curve of HP Librae (2020)
Journal Article
Solanki, S., Kupfer, T., Blaes, O., Breedt, E., & Scaringi, S. (2021). Periodicities in the K2 light curve of HP Librae. Monthly Notices of the Royal Astronomical Society, 500(1), 1222-1230. https://doi.org/10.1093/mnras/staa3240

We analyse Kepler/K2 light-curve data of the AM CVn system HP Librae (HP Lib). We detect with confidence four photometric periodicities in the system: the orbital frequency, both positive and negative superhumps, and the positive apsidal precession f...

Optical Variability of the Dwarf AGN NGC 4395 from the Transiting Exoplanet Survey Satellite (2020)
Journal Article
Burke, C. J., Shen, Y., Chen, Y.-C., Scaringi, S., Faucher-Giguere, C.-A., Liu, X., & Yang, Q. (2020). Optical Variability of the Dwarf AGN NGC 4395 from the Transiting Exoplanet Survey Satellite. Astrophysical Journal, 899(2), https://doi.org/10.3847/1538-4357/aba3ce

We present optical light curves from the Transiting Exoplanet Survey Satellite (TESS) for the archetypical dwarf active galactic nucleus (AGN) in the nearby galaxy NGC 4395 hosting a ~105 M⊙ supermassive black hole (SMBH). Significant variability is... Read More about Optical Variability of the Dwarf AGN NGC 4395 from the Transiting Exoplanet Survey Satellite.

The eclipsing accreting white dwarf Z chameleontis as seen with TESS (2019)
Journal Article
Court, J., Scaringi, S., Rappaport, S., Zhan, Z., Littlefield, C., Castro Segura, N., Knigge, C., Maccarone, T., Kennedy, M., Szkody, P., & Garnavich, P. (2019). The eclipsing accreting white dwarf Z chameleontis as seen with TESS. Monthly Notices of the Royal Astronomical Society, 488(3), 4149-4160. https://doi.org/10.1093/mnras/stz2015

We present results from a study of TESS observations of the eclipsing dwarf nova system Z Cha, covering both an outburst and a superoutburst. We discover that Z Cha undergoes hysteretic loops in eclipse depth – out-of-eclipse flux space in both the o... Read More about The eclipsing accreting white dwarf Z chameleontis as seen with TESS.

The Gaia/IPHAS and Gaia/KIS value-added catalogues (2018)
Journal Article

We present a sub-arcsecond crossmatch of Gaia DR2 against the INT Photometric H α Survey of the Northern Galactic Plane Data Release 2 (IPHAS DR2) and the Kepler-INT Survey (KIS). The resulting value-added catalogues (VACs) provide additional precise... Read More about The Gaia/IPHAS and Gaia/KIS value-added catalogues.

Magnetically gated accretion in an accreting ‘non-magnetic’ white dwarf (2017)
Journal Article
Scaringi, S., Maccarone, T., D’Angelo, C., Knigge, C., & Groot, P. (2017). Magnetically gated accretion in an accreting ‘non-magnetic’ white dwarf. Nature, 552(7684), 210-213. https://doi.org/10.1038/nature24653

White dwarfs are often found in binary systems with orbital periods ranging from tens of minutes to hours in which they can accrete gas from their companion stars. In about 15 per cent of these binaries, the magnetic field of the white dwarf is stron... Read More about Magnetically gated accretion in an accreting ‘non-magnetic’ white dwarf.
