Abstract
Vera C. Rubin Observatory, through the Legacy Survey of Space and Time (LSST), will allow us to derive a panchromatic view of variability in young stellar objects (YSOs) across all relevant timescales. Indeed, both short-term variability (on timescales of hours to days) and long-term variability (months to years), predominantly driven by the dynamics of accretion processes in disk-hosting YSOs, can be explored by taking advantage of the multiband filters option available in Rubin LSST, in particular the u, g, r, i filters that enable us to discriminate between photospheric stellar properties and accretion signatures. The homogeneity and depth of sky coverage that will be achieved with LSST will provide us with a unique opportunity to characterize the time evolution of disk accretion as a function of age and varying environmental conditions (e.g., field crowdedness, massive neighbors, metallicity) by targeting different star-forming regions. In this contribution to the Rubin LSST Survey Strategy Optimization Focus Issue, we discuss how implementing a dense observing cadence to explore short-term variability in YSOs represents a key complementary effort to the Wide-Fast-Deep observing mode that will be used to survey the sky over the full duration of the main survey (≈10 yr). The combination of these two modes will be vital to investigate the connection between the inner-disk dynamics and longer-term eruptive variability behaviors, such as those observed on EX Lupi-type objects.

N1 - Funding Information: Results from this project will, on one hand, provide improved physical insight to constrain existing and future magnetohydrodynamic models of young star–disk systems (e.g., Romanova et al. ; Zanni & Ferreira ; Orlando et al. ; Romanova et al. ; Zanni & Ferreira ; Bonito et al. ), and on the other hand, also inform the development of realistic 3D sketch models that describe the complex structure of these objects (S. Ustamujic et al. 2023b, in preparation). Printed versions of these 3D renderings, together with their visualization in virtual reality experiences connected to the physical processes investigated (see Orlando et al. ), will allow us to pursue a more inclusive scientific environment by increasing the accessibility of Rubin LSST's results for blind and visually impaired researchers. Moreover, thanks to their interactive and immersive nature (e.g., Jarrett et al. ), these tools will also prove invaluable in assisting the broader community of astronomers in their exploration and research of the complex astrophysical systems that can be investigated with Vera C. Rubin Observatory LSST. The authors acknowledge the support of the Vera C. Rubin LSST TVS SC that provided opportunities for collaboration and exchange of ideas and knowledge. We would like to acknowledge the support that John Stauffer (1952–2021) gave to this project since the preparation of the White Paper by Bonito et al. (). The authors are thankful for the support provided by the Vera C. Rubin Observatory MAF team in the creation and implementation of MAFs.
