What is a Bern model in planetary population synthesis?

Click For Summary

Discussion Overview

The discussion centers around the Bern model in planetary population synthesis, particularly its definition, origin, and references for further reading. Participants explore the model's application in the context of a Master's thesis and share insights on literature search strategies related to the topic.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant seeks clarification on what constitutes a Bern model in planetary population synthesis and requests references for further reading.
  • Another participant questions whether finding this information should be part of the thesis research process.
  • Several participants mention that the Bern model is associated with the University of Bern and is referenced in various academic papers, including a specific arXiv article.
  • Some participants express curiosity about the origin of the name "Bern," noting that it does not appear to be linked to a specific author's last name.
  • There is mention of the Bern model's development history, including its introduction in earlier studies and its application to planetary populations.
  • Participants discuss the importance of conducting thorough literature reviews as part of academic research and suggest strategies for improving search skills.
  • One participant identifies the existence of multiple Bern models, including one related to atmospheric sciences, which adds to the complexity of the discussion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specifics of the Bern model or its origin. Multiple viewpoints are presented regarding the model's definition and the research process involved in understanding it.

Contextual Notes

Participants express uncertainty about the specific first mention of the term "Bern model" in literature. There are references to various papers and the need for improved literature search strategies, but no definitive sources are agreed upon.

Who May Find This Useful

This discussion may be useful for graduate students and researchers interested in planetary formation models, literature review techniques, and the history of scientific models in astrophysics.

TL;DR
The planetary population synthesis are based on the Bern model and I want to know what it is.
Hello.
I'm writing my Master Thesis about planetary population synthesis and one of the chapters is about the different models.
I found that most of them are Bern models with some modifications.
What is a Bern model in planetary population synthesis and what references can I read about it?
Thanks for your cooperation.
 
Astronomy news on Phys.org
Shouldn't finding this out be part of your thesis?

How did you find the models for planetary system synthesis? What journals?

If you can post on PF, I suspect one might have access to Google, or other search engine.

Ditto to what V50 mentioned.
 
Out of curiosity (not knowing what the 'Bern model' was) I spent a minute or two Googling and found a description including references to the original and ongoing papers. Come on now!

Hi, Astronuc. Thanks for your answer.
That model was mentioned in
https://arxiv.org/abs/2007.05561
In this article the authors say "We base our study on the Bern model of planetary formation and evolution. This global model self- consistently computes the evolution of the gas and planetesimals discs, the accretion of gas and solids by the protoplanets, their internal and atmospheric structure, as well as interactions between the protoplanets and between the gas disc and the protoplanets."

But I want to know the origin of the name "Bern" because is not the last name of any author. When I googled about that model I found that there is a Bern Model in atmospheric sciences too. So, what means "Bern" model?
Thanks.

Thanks, Steve4Physics for your answer.
I also googled about the Bern Model and didn't found a kind of reference that you mentioned. Maybe I don't know strategies about what words to use for getting better results.
How did you google it and what specific reference you found with the original paper?
Thanks for your cooperation.

On the other hand, in the arxiv paper one cited, note the author affiliations, especially the institution 2, Physikalisches Institut, Universität Bern, Gesellschaftsstrasse 6, 3012 Bern, Switzerland

The five of six authors: Alexandre Emsenhuber, Christoph Mordasini, Remo Burn, Yann Alibert, and Willy Benz have affiliation with Universität Bern. Isn't this obvious?!

Also, in the arxiv paper, Section 2, The Bern Model, 2.1 History - "The original model was introduced in Alibert et al. (2004,2005a) for individual planets, then used in Mordasini et al.(2009a,b) for entire planetary populations."!

Looking elsewhere from a Google search, I quickly found the following:
At the University of Bern, the "Bern Model of Planet Formation and Evolution" has been continuously developed since 2003. Christoph Mordasini says: "Insights into the manifold processes involved in the formation and evolution of planets are integrated into the model." Using this Bern model the researchers were able to calculate the composition of this rock-forming material of the cooled-down star. "We then compared that with the rocky planets," Christoph Mordasini says.

If one is doing a MS program, those of us, who have so far responded, are left wondering why one is having trouble finding articles on the Bern model, or its origin. In writing a MS thesis, one task should be a reasonably thorough literature review, which is a skill that researchers must develop. The point of an MS degree is to demonstrate one can do the research, which includes performing literature searches.

Couldn't one ask one's faculty advisor? Or perhaps another professor in one's department?

Hmm. OK. I can’t remember my exact actions but, from an initial search for ‘bern model’, I found out that there there are two ‘Bern models’. One is a carbon-cycle climate model and the other is about planetary formation. (I’d not heard of either model, but I’m quite ignorant.)

Since you posted in the Astronomy and Astrophysics section and mentioned planets I realized that you were referring to planetary formation.

So I did a more specific Google search for ‘bern model planetary formation’.

After exploring a few matches/links (can't remember exactly what links I clicked) I found this, for example:
https://export.arxiv.org/pdf/2007.05561
which even includes a history of the Bern model.

It’s not rocket science (haha).

Thanks for your answer.
You are right about the skill for searching texts or references: I never thought about the university of the authors. Now, I'm thinking of the "Copenhague" interpretation of the Quantum Mechanics. Obviously, I have to improve that skill.

About this:
Also, in the arxiv paper, Section 2, The Bern Model, 2.1 History - "The original model was introduced in Alibert et al. (2004,2005a) for individual planets, then used in Mordasini et al.(2009a,b) for entire planetary populations."!

I have the articles: all of them and many others. A lot! The problem is that I was looking for an article in which that model was named "Bern Model" for the very first time. It's about skills and I have to develop them. I'm in the process.
Again, thanks for your answer.
This topic can be closed.
Have a nice day.

Look at where many of the authors of the paper you referenced are from, and look at where many of the authors of the Bern model in the references of that paper are from.
