Exploring Mass Transfer Mechanisms in Symbiotic Systems
The Astrophysical JournalWe define two regimes of the parameter space of symbiotic systems based on the dominant mass transfer mechanism. A wide range of white dwarf (WD) mass, donor mass, and donor radius combinations are explored to determine the separation for each parameter ...

The role of venture‐financed startups in innovation for US agriculture
American Journal of Agricultural Economics, EarlyView.Abstract To evaluate the role played by startup companies in the innovation ecosystem of US agriculture, we compile a unique dataset of 6024 new entrants founded 1987–2019 that details their financing lifecycles, annual economic performance, and patenting activities.

Empowering Circular Startups: Unveiling the Blueprint for Circular Business Models
Business Strategy and the Environment, EarlyView.ABSTRACT Circular startups are increasingly recognized as key drivers in the transition toward a circular economy. Yet the business models (BMs) through which these startups operationalize circularity remain poorly understood, limiting the ability of entrepreneurial ecosystem actors to offer effective support.

Greening the Bottom Line: Public Funding for Circular Economy Initiatives and Financial Stability
Business Strategy and the Environment, EarlyView.ABSTRACT Public funding for circular economy (CE) initiatives plays a crucial role in shaping corporate financial performance, yet its effects remain underexplored. Grounded in the resource‐based view (RBV) of the firm, this study investigates the financial impact of CE funding on private firms, using Portugal as a case study. It analyses the financial

Symbiotic Stars as Possible Progenitors of SNe Ia: Binary Parameters and Overall Outlook [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractSymbiotic stars are interacting binaries in which the first-formed white dwarf accretes and burns material from a red giant companion. This paper aims at presenting physical characteristics of these objects and discussing their possible link with progenitors of Type Ia supernovae.

Spectroscopy of the symbiotic binary CH Cygni from 1996 to 2007 [PDF]
Astronomy & Astrophysics, 2009 We monitored a set of emission lines in the optical spectra of CH Cyg using the 1.5-m telescope at the Tartu Observatory, Estonia. Most of the spectra were registered in the H alpha region, but other Balmer lines and lines of He, N, O, and Fe were also investigated in terms of their equivalent widths, radial velocities, and absolute fluxes. The spectra
