Journal Article
Fratta, M., Scaringi, S., Monguió, M., Pala, A., Drew, J., Knigge, C., …Gandhi, P. (2022). Spectroscopic follow-up of a subset of the Gaia/IPHAS catalogue of Hα-excess sources. Monthly Notices of the Royal Astronomical Society, 518(3), 3301-3311. https://doi.org/10.1093/mnras/stac3216

State-of-the-art techniques to identify Hα emission-line sources in narrow-band photometric surveys consist of searching for  Hα excess with reference to nearby objects in the sky (position-based selection). However, while this approach usually yield... Read More about Spectroscopic follow-up of a subset of the Gaia/IPHAS catalogue of Hα-excess sources.

XGAPS: a sub-arcsec cross-match of galactic plane surveys (2022)
Journal Article
Scaringi, S., Monguió, M., Knigge, C., Fratta, M., Gänsicke, B., Groot, P., …Toloza, O. (2022). XGAPS: a sub-arcsec cross-match of galactic plane surveys. Monthly Notices of the Royal Astronomical Society, 518(2), 3137-3146. https://doi.org/10.1093/mnras/stac3353

We present a sub-arcsec cross-match of Gaia Data Release 3 (DR3) against the INT Galactic Plane Surveys (IGAPS) and the United Kingdom Infrared Deep Sky Survey (UKIDSS). The resulting cross-match of Galactic Plane Surveys (XGAPS) provides additional... Read More about XGAPS: a sub-arcsec cross-match of galactic plane surveys.

Localized thermonuclear bursts from accreting magnetic white dwarfs (2022)
Journal Article
Scaringi, S., Groot, P., Knigge, C., Bird, A., Breedt, E., Buckley, D., …Timmes, F. (2022). Localized thermonuclear bursts from accreting magnetic white dwarfs. Nature, 604(7906), 447-450. https://doi.org/10.1038/s41586-022-04495-6

Nova explosions are caused by global thermonuclear runaways triggered in the surface layers of accreting white dwarfs1,2,3. It has been predicted4,5,6 that localized thermonuclear bursts on white dwarfs can also take place, similar to type-I X-ray bu...

SU Lyn - a transient symbiotic star (2021)
Journal Article
Iłkiewicz, K., Mikołajewska, J., Scaringi, S., Teyssier, F., Stoyanov, K. A., & Fratta, M. (2022). SU Lyn - a transient symbiotic star. Monthly Notices of the Royal Astronomical Society, 510(2), 2707-2717. https://doi.org/10.1093/mnras/stab3637

SU Lyn is a binary system composed of a white dwarf and a red giant star. Although it is known to be bright and variable at X-ray wavelengths, the optical counterpart of the source appeared as a single red giant without prominent emission lines. Beca...

An accreting white dwarf displaying fast transitional mode switching (2021)
Journal Article
Scaringi, S., de Martino, D., Buckley, D., Groot, P., Knigge, C., Fratta, M., …Papitto, A. (2022). An accreting white dwarf displaying fast transitional mode switching. Nature Astronomy, 6, 98-102. https://doi.org/10.1038/s41550-021-01494-x

Accreting white dwarfs are often found in close binary systems with orbital periods ranging from tens of minutes to several hours. In most cases, the accretion process is relatively steady, with significant modulations only occurring on timescales of...

Population-based identification of H α-excess sources in the Gaia DR2 and IPHAS catalogues (2021)
Journal Article
Fratta, M., Scaringi, S., Drew, J., Monguió, M., Knigge, C., Maccarone, T., …Gänsicke, B. (2021). Population-based identification of H α-excess sources in the Gaia DR2 and IPHAS catalogues. Monthly Notices of the Royal Astronomical Society, 505(1), 1135-1152. https://doi.org/10.1093/mnras/stab1258

We present a catalogue of point-like H α-excess sources in the Northern Galactic Plane. Our catalogue is created using a new technique that leverages astrometric and photomeric information from Gaia to select H α-bright outliers in the INT Photometri...
